Simple Shells
After you have specified a name, associated surfaces, and the
Simple shell type in the
Shell Definition dialog box, you need to provide
Creo Simulate with the following information in the
Properties area:
• Thickness—You can specify the thickness of your shell as a positive numerical value. You can
select units of thickness from the adjacent drop-down list or accept the default units. When
Creo Simulate creates the shell elements for the surface, it applies the thickness you specify equally on both sides of the selected surface. For example, if you specify a shell thickness of 1,
Creo Simulate places 0.5 on the top side of the surface and 0.5 on the bottom side.
The thickness field is a
parameter-capable edit field. This field accepts
Creo Parametric parameters, which you can select from a displayed list.
You can also enter an expression as a thickness value.
The shell thickness you assign to an individual quilt surface overrides any other thickness that might be assigned to that quilt surface as part of another shell definition.
• Material—Specify the material of the shell. Click the arrow to display a drop-down list of material properties already associated with your model. If you do not see what you want in the drop-down list, click More to display more materials, or to create a new material.
The part material is selected by default, for parts. For assemblies, no material is selected by default.
You can only use isotropic materials with simple shells, so the drop-down list contains only those. If you select a non-isotropic material after clicking More, the software reminds you that you must use isotropic material properties with simple shells.
