Importing Support Reactions

This load wizard allows you to import the reaction forces of nodal supports of another model and to apply them as loads. This way, models can be digitally coupled as structural models with item lists. The linked models are managed in the Dependent Models tab of the model's Base Data dialog box.

Important

This load wizard is available if the model is integrated into a project Dlubal Center.

Tip

For practical information on the transfer of support reactions, see the FAQ Using Load Wizard "Import Support Reactions".

Model

In the Model tab, define the model whose support reactions you want to import. In the Load Wizard, the "source model" is referred to as 'Connected model'. Please note the following:

  • The current model and the connected model must be in the same Projekt .
  • Both models must have different model IDs (see chapter Modellparameter ).
  • It is not necessary to open the connected model.
  • The connected model must be saved with results. If this is not the case, it is not possible to import any support reactions.

Select the "source model" in the 'Connected model' list (see Image New Load Wizard | Import Support Reactions). You can also select it in Dlubal Center by using the Dlubal Center button.

Objects

In the Objects tab, you can assign the support reactions of the connected model to the nodes of the current model.

Import from Supported Objects

In the current state of development (August 2023), only the manual object connection type is available. The objects must be user-defined.

Import from Connected Model's Objects

All nodes for which support reactions are available in the connected model are included by default for the import. If you want to consider only certain nodes, clear the 'All' check box. Then, you can enter the numbers of the supported nodes for the source model.

Info

The reactions of member supports cannot be imported.

Import to Current Model's Objects

Specify the numbers of the nodes on which the reactions of the connected model should act as loads. You can use the Select Individually button to select the objects in the work window.

Important

The support reactions are strictly assigned according to the order of numbers, as defined in the two dialog sections, and not – as in RFEM 5 – according to the geometric position in the model.

Loading

The Loading tab manages the assignment of loads in the load cases of both the connected model and the current model.

Categories

The 'Loading connection type' determines the way how load cases are linked between both models. The list includes two entries:

  • Manually: In the 'Connected Loading' dialog section, you can define how the load cases of the connected model should be connected to those of the current model (see image Selecting Connected Loading).
  • Automatically: The program assigns the support reactions of the connected model by load case to the corresponding LC numbers of the current model.

Connected Loading

If the 'Manually' loading connection type is set, you can individually specify how the load cases of the connected model are to be linked with those of the current model: Select the relevant load case numbers in the lists of the 'From Loading' and 'To Loading' columns (see image Selecting Connected Loading). These options are not available for the automatic assignment. RSTAB assigns the support reactions by number to the corresponding load cases.

In the 'Direction' list, you can specify which component(s) of the support reactions should be considered for the import. Both forces and moments are available for selection.
