ushl_LS-Dyna_Fortran

Basics to implement user-defined shell elements (ushl, uel) in LS-Dyna with Fortran

Focus here is on 2D elements for plane strain and axisymmetry, not on actual shell elements

Generalised interface for use of separate element subroutines for 2D plane strain and axisymmetry

If you use a separate subroutine for the element formulation or e.g. AceGen to generate the element routine, I can recommend the general interface stated in "ushl_e101_generalInterface.f".
