  • Answer

    In the "Edit Load Cases and Combinations" dialog box, you can specify in the bottom right of the "Combination Expressions" tab which method of analysis should be used as the basis for the generated load combinations. By default, the linear calculation according to the geometrically linear analysis is preset for load cases and the nonlinear calculation according to the second-order analysis for load combinations.

    Thus, you can quickly determine whether the load case or the load combination is calculated according to the geometrically linear, second-order, or large deformation analysis. The postcritical analysis option allows you to carry out the stability analysis according to the large deformation analysis with regard to the post-critical failure of the entire structure.

    In case the model includes cable members, the calculation according to the large deformation analysis is preset in all cases.
  • Answer

    Yes, that is possible. Simply select the structure to be copied. Make sure that the line releases and all released objects are also selected. Now you can create a copy with the 'Move and Copy' function.
  • Answer

    The RWIND Simulation program is protected against unauthorized use. If the software key is authorized, the program is only authorized for a specific activation period, which must be defined by the user. After this period, the program automatically switches to demo mode; the previously used license is again freely available for a new activation. To avoid reactivation on the same standalone computer, it is possible to renew the license online (computer is connected to the Internet) by specifying a new activation period before the activation period expires. To do this, proceed as follows:

    1. Run RWIND Simulation 'As Administrator'. To do this, right-click the RWIND Simulation icon and select 'Run As Administrator'.

      Figure 01 - Program Start

    2. Select the 'RWIND Simulation - License and Authorization' function in the "Help" menu.

      Figure 02 - License and Authorization Settings

      This opens the 'RWIND Simulation 1.xx Authorization Status' dialog box.

    3. Check in the 'RWIND Simulation 1.xx Authorization Status' dialog box whether an active software key authorization is available. This is the case if the 'Software Key' option is selected in the 'Authorization Method' section, and an active authorization is indicated by a green dot in the 'Authorization Status' section.

      Figure 03 - Authorization Status

      If the check turns out to be negative and a red dot is displayed, no RWIND Simulation license based on a software key is activated on the single-user computer. As a result, the activation period for a license cannot be extended.

      If the specified requirements are met, click the 'Extend Activation Online' button. The 'Renew Activation - Online' dialog box appears.

    4. The 'Renew Activation - Online' dialog box shows the license specification to be extended.

      Enter your online activation key based on your contract documents and define the new activation period in the date field.

      Then, start the online renewal with the function 'Renew Activation Now'

      Figure 04 - Extension of Activation

      This opens the 'RWIND Simulation 1.xx' dialog box.

    5. In the 'RWIND Simulation 1.xx' dialog with the confirmation prompt about the planned modification select 'OK' to finally change the activation period.

      Figure 05 - Confirmation Prompt

      After successfully changing the activation period, you receive a confirmation message and can use the program without restrictions.
    Thus, your purchased license is used in our system for the newly defined activation period. During this time, it is not possible to activate the RWIND Simulation program with the activation key on any other computer. The assignment of the license in our system ends with a proper deactivation or after the defined activation period has expired.

    To avoid unnecessary license assignments in our system due to unexpected computer problems on your part (defect, loss, hardware replacement, change of employees, etc.), we recommend keeping the activation period as short as possible.

  • Answer

    The RWIND Simulation program is protected against unauthorized use. The application works without restrictions on the single-user computer on which the software key-based license is activated. To release the assigned license (e.g. for use on a different single-user computer), the license can be deactivated again offline via email on the license-holding single-user computer. To do this, proceed as follows:

    1. Run the RWIND Simulation 'As Administrator'. To do this, right-click the RWIND Simulation icon and select 'Run as Administrator'.

      Figure 01 - Program Start

    2. Select the 'RWIND Simulation - License and Authorization' function in the 'Help' menu.

      Figure 02 - License and Authorization Settings

      This opens the 'RWIND Simulation 1.xx Authorization Status' dialog box.

    3. Check in the 'RWIND Simulation 1.xx Authorization Status' dialog box whether an active software key authorization is available. This is the case if the 'Software Key' option is selected in the 'Authorization Method' section and an active authorization is indicated by a green dot in the 'Authorization Status' section.

      Figure 03 - Authorization Status

      If the check is negative, and a red dot is displayed, no RWIND Simulation license based on a software key is activated on the single-user computer. Consequently, no license can be deactivated.

      If the above requirements are met, click the 'Deactivation via E-Mail' button. The 'Deactivation of RWIND Simulation' dialog box appears.

    4. The 'Deactivation of RWIND Simulation' dialog box explains the deactivation process.

      Select the 'Deactivate RWIND Simulation Now' function.

      Figure 04 - Email Deactivation

      This opens the 'RWIND Simulation 1.xx' dialog box.

    5. In the 'RWIND Simulation 1.xx' dialog box, select 'Yes' for the license deactivation.

      Figure 05 - Confirmation Prompt

      After successful deactivation, you will receive a confirmation message. You can use the program only in demo mode now.

      The dialog box 'Deactivation of RWIND Simulation' opens again.

    6. Deactivation code is now displayed in the ‘Deactivation of RWIND Simulation’ dialog box. Copy this text block to the Windows clipboard with the 'Copy to Clipboard' function and then paste the code into a blank e-mail with [Ctrl]+[V] or the Windows paste function. Send this email to support@dlubal.com to complete the license deactivation.

      Figure 06 - Sending Deactivation Code

      With this code, we document a proper deactivation in our system.
    You can now reactivate the released license on another single-user computer.

  • Answer

    The RWIND Simulation program is protected against unauthorized use. The program can be authorized offline (computer is not connected to the Internet) by activating an email. To do this, proceed as follows:

    1. Run the RWIND Simulation 'As Administrator'. To do this, right-click the RWIND Simulation icon and select 'Run as Administrator'.

      Figure 01 - Program Start

    2. Confirm the authorization check with the 'Activate Now' function.

      Figure 02 - Authorization Check

      This opens the 'RWIND Simulation 1.xx Demo Authorization Status' dialog box.

    3. In the 'RWIND Simulation 1.xx Demo Authorization Status' dialog box, select the 'Software Key' option in the Authorization Method area and click the 'Activation via E-Mail' function in the lower part.

      Figure 03 - Email Activation

      This opens the 'Activation by E-Mail' dialog box.

    4. In the 'Activation by E-Mail' dialog box, enter your license information (license number and/or name and address of the institution that purchased the program license) based on your contract documents.

      Further, enter a user-defined description of the workstation to be activated under 'Description of Workspace' and the RWIND Simulation level with an expiry date of the activation to be carried out under 'Required Authorization'.

      Then confirm your entries by clicking the 'Generate Request Code' function.

      Figure 04 - Generating Request Codes

      This opens the 'RWIND Simulation 1.xx Demo' dialog box.

    5. Check the entries made in the 'RWIND Simulation 1.xx Demo' dialog box. If they comply, confirm the dialog box with 'OK'.

      Figure 05 - Checking Entries

      This opens the 'Activation by E-Mail' dialog box.

    6. The 'Activation via E-Mail' dialog box consists of three parts. In the 'Step 2' tab, the required request code is displayed on the left. Copy this text block to the Windows clipboard with the 'Copy Request Code' function and then paste the code into a blank e-mail with [Ctrl]+[V] or the Windows paste function. Send this email to support@dlubal.com for further processing.

      Figure 06 - Sending Request Code

    7. You will receive an activation code from us. In the dialog box, go to the 'Step 3' tab and enter this code in the 'Activation Code' field.

      Then, start the activation process by clicking the 'Activate Now' function.

      Figure 07 - Program Activation

      After successful authorization, you will receive a confirmation message and it is possible to use the program without any restrictions.
    This offline email activation occupies the license you have purchased for the defined activation period in our system. During this period, it is not possible to activate the RWIND Simulation program with the same license on any other computer. The assignment of the license in our system ends with a proper deactivation or after the defined activation period has expired.

    Afterward, the activation process can be carried out again on the same or a different computer. Please note that e-mail request codes can only be used once for activation. To reactivate, a new request code must always be sent to us.

    To avoid unnecessary license assignments in our system due to unexpected computer problems on your part (defect, loss, hardware replacement, change of employees, etc.), we recommend that you keep the activation period as short as possible.

  • Answer

    No, this is not possible.

    The member elastic foundation is basically constant over the length of the member.

    If you want to enter a variable member foundation based on the height of the bored pile, you have to divide the bored pile into individual members and specify different constant foundations on the individual members. Thus, the linear distribution of a foundation can be approximately simulated.

    In addition to the components for describing the load type, location, and language, the request URL also includes components for describing the user's identity. The 'login' component describes the user's e-mail address and the 'hash' component describes a hidden password. For a functional login, the e-mail address must be saved in a valid Dlubal account.

    If you do not have a Dlubal account yet, you can create it on this page:

    https://www.dlubal.com/en-US/extranet/create-new-account

    After having successfully logged in to your Dlubal Account in the top left corner of our website,

  • Answer

    When modeling a glass pane, especially an insulating glass pane, it is necessary in RFEM to pay special attention to the boundary lines that must consist of four lines only.
    If possible, you should avoid the division of lines since the calculation cannot be performed anymore. In that case, the corresponding warning message will be displayed before the calculation.
    If special intermediate nodes are required on the line, make sure that they do not divide the original line when creating them.
    However, if the line is divided anyhow the structure can be restored by using the "Delete Node and Merge Joined Members" command.
    In exceptional cases, you can deactivate using the layered mesh in the details of the composition. This option has been specifically implemented for double-curved panes.

    In the Result Diagrams dialog box, it is possible to create average regions to prepare the results for engineering. This function is available with the 'Edit Average Regions' button. The dialog box in Figure 1 opens.

    Define the average regions in the table columns on the left; entries for Start, End, and Length are interdependent. Each region can be activated separately. The 'Use for Results' section controls for which deformations, internal forces, stresses, or strains a smoothing is to be performed. The smoothing can be constant or linear for all average regions.

    Furthermore, an average line can be displayed over the entire result diagram via the button of the same name (Figure 2).

    The integral of the average region is displayed if the 'With Result Interpretations' checkbox is selected in the settings of the result diagrams (Figure 3).
