The Main tab manages the basic model parameters.
Model
The 'Model name' must be specified, as it is also the file name of the model. However, the 'Model description' is optional. It allows you to describe the model briefly. The description appears in the printout report, but has no other function.
Project
In the 'Project name' list, you select the project folder where you want to create the model. Use the
button to create a new project. The 'Create New Project' dialog box appears where you enter relevant project data.
The
button gives access to the Dlubal Center. There, you can set a different project than the current one (see Chapter
Models
).
The 'Project description' and the 'Folder for data' of the selected project are displayed for information.
Type of Model
The model type controls whether a spatial, planar, or one-dimensional model is analyzed. If the model available is not 3D, you can restrict the input parameters to reduced coordinates and degrees of freedom in this dialog section.
The '2D | XZ' types are suitable for walls and panes when loading acts only in the direction of the surface plane. These types are also recommended for planar beam structures. The '2D | XY' types represent planar surface structures, such as plates that are stressed perpendicular to the surface plane. The '3D' options allow for spatial calculation of the planar system; for example, if you use unsymmetrical cross-sections with rotation angles such as wind bracings.
'1D | X' types allow you to model one-dimensional beam structures such as continuous beams. Again, the '3D' option allows for the spatial calculation of rotated cross-sections.
It is also possible to change the model type subsequently. However, this may result in data loss; for example, if you reduce a 3D model to a plate.
Initialization of New Model
With the 'Blank' default setting, you must define all model data from scratch. Alternatively, you can preset a template. The following options are available:
- Existing model as a copy: The copy of a file is preset.
- Template: You can use a template file that you have saved as Template.
- Block: You can preset a Block as a model component.
Select the template or block from the list below. Use the
button to access the Dlubal Center, which provides an overview of all templates.
Initial Building Grid
A Building Grid facilitates the model input: The intersection points of a planar or spatial grid consisting of lines represent definition points for lines, members, and surfaces.
In the list, you find four preset types for building grids that you can adjust, if necessary, and use for input.
Main Objects to Activate
In this dialog section, you can control the basic object types to be used in the model:
If you deactivate an entry, the corresponding entries do not appear in the navigator or tables.
Comment
Here, you can enter text to add a comment to the model. This comment also appears in the printout report.
