I am doing web crippling analysis of sigma section and while running the analysis this error occurs. ( see attachment) Please let me know any possible way to overcome that issue...
There are several reasons for this error, you should first check your element type. then check the geometry, boundary conditions, material and interaction properties you can also use penalty contacts instead of kinematics or probably you need to refine your mesh.
You first find which units have problems in the output results,then check what is wrong with these units and whether they are not selected during definition.
