Code_Aster can really replace in many cases traditional solvers, let's try with a simple problem. This problem will look into a specific contact type, called CGAP in Nastran™ and unilateral contact ("LIAISON_UNIL") in Code_Aster. This case is taken from a publicy available example on the internet, but the original source is probably this one, for all due credit. … Continue reading Nastran to Code_Aster: nonlinear gap elements
