Import simulation entities

Before you import simulation entities, be sure that you can find and identify:

  • The target simulation. Typically, this is the top-level assembly FEM simulation.

  • The source simulation that contains the entities you want to import.

  • The component FEM or subassembly FEM referenced by the source simulation.

  • The entity types you want to import.

To import simulation entities:

  1. In the Simulation Navigator, ensure that the target simulation is the currently displayed and work part.

  2. In the Simulation Navigator, select the component FEM or subassembly FEM node that references the source simulation.Hold Ctrl and click to select multiple instances of a component FEM or subassembly FEM.If your simulation contains only a single FEM, select that FEM.

  3. Right-click the selected node and choose Import Simulation Entities, or choose FileImportSimulation Entities.The Import Simulation Entities dialog box appears.

  4. In the Source Simulation group, select the simulation you want to import.You can choose a loaded simulation file from the list of simulation file names or click Browse next to Open Simulation to navigate to and select the source simulation file.Tip: To help you find a simulation file in the list of loaded simulations, in the Search box, type a string you want to use for the search and click Search.

  5. In the Entities to Import group, select the types of entities you want to import. Do one of the following:To import all entities associated with the previously selected simulation, select Import All Entities check box.From the Entity Type list, select the type of entity you want to import, and then from the Entity List, select the specific entities.For some entity types, such as loads and constraints, you can select the Enable Graphical Selection check box and select the entities from the graphics window instead of the list.

  6. If you set Entity Type to Result Probe, select the source and target solution.From the Source Solution list, select a solution that contains the result probe.From the Target Solution list, select the target solution into which to import the result probe or select None. The type of target solution should match the source solution (for example, Thermal or Structural).If you select None, the software imports the source solution without boundary conditions.

  7. To select an entity for import, in the Entity List select the Status to change it to , which means it is now selected.To remove an entity from import, in the Entity List, select the Status to change it to , which means it is no longer selected.

  8. (Optional) In the Boundary Condition ID Management group, in the Specify Offset box, specify a number to be added to the names of the boundary conditions as they are imported. This offset is added to the label of boundary conditions (providing one exists) to resolve conflicts after import. For more information on this renumbering, see Renumbering of boundary conditions.

  9. In the Advanced Options group, specify how the software resolves naming conflicts between expressions in the simulation entity that you are importing, and existing expressions in the simulation.For more information on these options, see Importing simulation entities.

  10. If you select the Keep Both option in the Advanced Options group, in the Suffix Key box, specify the text string that the software appends to the name of the expression in the simulation entity whose name conflicts with an existing expression.

  11. Click OK.The software imports the selected entities to the target simulation, runs correspondence checks, and reattaches entities as appropriate. The imported entities appear in the corresponding containers in the target simulation. If specified in the String to prepend simulation entity names box, the imported entity names are prepended with the name entered. By default, it is the name of the source simulation.Note: For imported solutions, the software imports all result probes associated with the solution.

  12. Check the status of imported entity in the Simulation Navigator:For boundary conditions, if the status of imported boundary conditions is unattached, you may need to edit the boundary conditions to reattach them to geometry or FE entities. See Edit a boundary condition.For result probes, if the status of the imported result probes is asleep, you may need to edit the result probes. See Correspondence checks and reattachment.

  13. To use imported boundary conditions in a solution, in the Simulation Navigator, drag loads, constraints, and simulation objects to the corresponding container in the solution or subcase.
