How can I apply Cyclic loading in ANSYS Mechanical APDL as a second Load step after a Static 1st Load step?

I am simulating a masonry wall under in-plane cyclic loading. Before the cyclic load is applied, it must be loaded with gravity direction surcharge load (or pre-compression). However, whenever I...

Why the Stresses in solid elements do not remain within the defined Drucker Prager's stress limits while analysis in ANSYS under some conditions?

The question is long: I am modelling a masonry wall in ANSYS APDL. The masonry units are "expanded" to half mortar thickness on each side and joined to the adjacent ones using Surface-to-Surface...

How to define Tensile and Shear Strength of SOLID65 in ANSYS Mechanical APDL?

I am modeling a brick masonry wall in ANSYS. The adjacent bricks (SOLID65 elements) are "joined" by surface to surface contact elements with certain normal and opening stiffness. I defined...

How do I solve a Solver Pivot Error in an ANSYS model with minor gaps between solid elements?

Hi, I'm currently modeling a brick wall in Ansys. I'm modeling the bricks as discrete elements and replaced the mortar with non-linear spring elements (Combin39). There is a 2mm gap between each...
