Checking Geometry Validity

Before you set up a simulation, you can check the validity of the geometry in 3D-CAD.

As invalid geometries can cause problems during the meshing process, you are recommended to verify that the geometry is valid before you set up the simulation—particularly when using imported geometries.

In 3D-CAD, you can check the validity of an entire geometry, as well as specific bodies or faces. Specifically, you can check the validity of the following types of bodies:
  • BRep (Boundary Representation) sheet bodies
  • Facet sheet bodies
  • BRep (Boundary Representation) solid bodies

  • Facet solid bodies

Use one of the following actions to run a validity check:

  • In the feature tree, right-click a body that you want to check and select Check Validity.
  • In the feature tree, right-click the model node and select Check Validity.
  • In the 3D-CAD View scene, right-click on a face and select Check Validity from the Body group box.
  • In the 3D-CAD View scene, right-click on a face and select Check Validity from the Face group box.

    A message with the results of the validity check is printed in the Output window. For example, if a body is not valid, the following message is displayed: 

    Body Body 2 is not valid.

Checking Validity Upon Import

You can automatically check the validity of a geometry when you import it into 3D-CAD. See Importing Geometry into 3D-CAD.
