In PAM-CRASH2G, use the Map Mid-Mesh Thickness tool to estimate and assign a mid-mesh thickness to elements or components. You can also maintain the thickness for a contact (TCONT) to be the same as element thickness (H).
Elements
If you select elements, a thickness is assigned to the attribute T of the card SHELL and TSHEL.
Thickness on Components
If you select thickness on components, HyperMesh will assign a thickness to the attribute H of the card PART based on SHELL, TSHEL, and MEMBR.
Thickness for contact
If you enable the Contact Thickness checkbox, under Components, a thickness value is assigned to the TCONT attribute, which is the same as the thickness value of H of the card PART on SHELL, TSHEL, and MEMBR.
