Solid 185

The document defines material properties and contact parameters for a solid element and contact elements in a finite element analysis. It specifies properties like modulus of elasticity, Poisson's ratio, and temperature-dependent tabular data for the solid element. Contact properties like normal and tangential stiffness are defined for the contact elements through real constant modifiers. Node sets for the top and bottom surfaces are identified as the source and target for contact generation between the defined nodes.
