Creating a Partial Shell Mesh
You can partially shell-mesh a FEM model. This enables you to generate the mesh on the portion of the model where surface pairs are properly defined, ignoring unpaired surfaces. See Strategy: Working with Partial Shell Meshes.
The software distinguishes two types of problem surfaces:
Unpaired surfaces — Surfaces omitted in the process of defining shell pairs.
Unopposed surfaces— Surfaces that can occur when geometries of paired surfaces are not exactly the same. As a result, leftover surfaces may appear in the shell model.
When you create a partial shell mesh, you can either use the unopposed surfaces in the shell model or ignore them, depending on the state of the Remove Unopposed Surfaces check box on FEM Mesh Settings dialog box in FEM mode or the AutoGEM Settings dialog box in native mode.
To eliminate unopposed surfaces to generate a full mesh, use one of the methods recommended for pairing unopposed surfaces.
When you attempt to compress the model and the system detects unpaired surfaces, the following events occur:
The system highlights the unpaired surfaces and asks you if you want to mesh only paired surfaces.
To halt the process, click the stop sign displayed in the lower right corner of the Creo Parametric window.
To continue, proceed to the next step.
You can visually investigate the shell model using options in the Simulation Geometry dialog box.
To mesh only the paired surfaces, click Home and then click the arrow next to Mesh. Select Midsurface. Click Mesh.
