I'm currently running a 2D Steady Linear Heat Transfer Analysis on a squared shell (DS4 elements) in ABAQUS. I'm able to run the simulation without the Remeshing Rule. However, introducing a Remeshing Rule I always get "Error in job: PROGRAM IS ASKED TO INVERT A SINGULAR MATRIX". I have tried several different default as well as user-defined remeshing parameters (initial mesh, sizing method, constraints). What am I doing wrong?
