Checking the completeness of your model prior to a solve

Use the Model Setup command to verify that your model contains all the necessary items for the analysis. The software verifies, for example, that the model contains elements, loads, constraints, and materials. The software displays the results of a check in a separate Information window, along with an error summary for each topic.

You can also use the Model Setup Check option in the Solve dialog box to control whether you want the software to automatically verify the completeness of your model prior to beginning the solve.

If you do not want the software to check the completeness of your model, clear the Model Setup Check check box.

Checks for assembly FEM labeling conflicts

You can use the Check for Label Conflicts check box in the Model Setup dialog box to check for:

• Node, element, coordinate system, physical property, group, and ply labeling conflicts between component FEMs.If Model Setup detects assembly FEM label conflicts, you can use the Assembly Label Manager to resolve those conflicts. For more information, see Assembly Label Manager dialog box.

• Coordinate system, physical property, and group label conflicts between the Simulation file and the component FEMs.If Model Setup detects Simulation file label conflicts, you can use the Simulation Label Manager to resolve those conflicts. For more information, see Simulation Label Manager dialog box.

Checks for element associated data

The Model Setup command also evaluates the validity of any defined element associated data in your model. For example, if your model contains Nastran CQUAD4 elements with a specified material orientation vector, the Model Setup command verifies that the material orientation definitions are valid.

Checks for unit systems conflicts

The Model Setup command checks for conflicts between the solver unit system and an external result file unit system. For example, if your model contains a load, such as Force from External File, Enforced Motion from External File, Surface Dipole, or Fan Noise, that references an external result file, the Model Setup command verifies the match of the unit systems.

Note:

If Model Setup detects that the unit systems do not match, you can use the Edit Advanced Solver Options to resolve the conflict. For more information, see Adjust advanced solver options.

Check for unmeshed bodies

The Model Setup command checks for any unmeshed bodies in your model and lists them in the error summary. You can use the Issue a Model Check Error Message for Unmeshed Bodies customer default to control what happens if the software finds unmeshed bodies:

• If you select the Issue a Model Check Error Message for Unmeshed Bodies default, the software reports the unmeshed bodies as errors and aborts the solve.

• If you do not select the Issue a Model Check Error Message for Unmeshed Bodies default, the software reports the unmeshed bodies as warnings and the solve proceeds.

Identifying unmeshed bodies prior to a solve is particularly helpful when you are working with complex models that contain numerous bodies.

Check of thermal-flow functions

The Model Setup command checks thermal-flow functions in thermal and Multiphysics coupled simulations to verify that the boundary condition IDs are valid. For example, if you have an expression including STI(3), model setup will verify that a thermal stream load with an ID of 3 exists.

The Model Setup command checks for the referenced IDs of the following thermal-flow functions:

• Thermal Stream Functions: MIX, MMIX, SA, SA2, SMO, SP, SSV, STI, STMO, STO, PWR

• Thermal Void Functions: VA, VP, VSV, VT, PWRV

• Thermal Zone Functions: ZA, ZP, ZSV, ZT
