Mid-Mesh Thickness Behavior in LS-DYNA

In LS-DYNA, you can use the Map Mid-Mesh Thickness tool to estimate and assign a mid-mesh thickness to elements or to each node on corresponding elements.

Nodal Thickness on Elements

If you select Nodal thickness on elements, HyperMesh assigns a thickness to each node on corresponding elements. A thickness will be assigned to nodes that have the following THIC attributes of the *ELEMENT_SHELL_THICKNESS card: THIC1, THIC2, THIC3 and THIC4.

Elements

If you select elements, HyperMesh assigns a thickness to the THIC1, THIC2, THIC3, and THIC4 fields of the card *ELEMENT_SHELL_THICKNESS. A single value thickness, that was defined in the MidSurf mesh tool, will be assigned to all of the thickness attributes of the card.

Note:

If the element is of type TRIA, then a THIC3 thickness will be assigned to THIC4. If you change the view to 2D Detailed Element Representation from the Visualization toolbar, then THIC4 will be ignored for TRIA elements.

Properties on Components

If you select Properties on components, Engineering Solutions will:

•	Create multiple properties, based on the thickness, named thickness_t with SHELLSECTION card images. "t" is the estimated thickness value.

•	Create corresponding materials and components named thickness_t.

•	Assign a property to the components that were created.

Write INCLUDE_STAMPED_PART

If you select this check box, Engineering Solutions will create an include file for each component selected for the run. Engineering Solutions will also create a system collecter with the card image includeStampedPart, and associate it to the created include file.

This option is only valid for the Thickness output options Elements and Nodal thickness on elements. It is not supported for Properties on Components.
