Solver not starting for solution

    • krs19

      I am doing a 2d simulation of adsorption and desorption of carbon where I am using 4 UDS to store calculated values for the adsorption and desorption.

      But when I am running the simulation I am encountering the following error

      Divergence detected in AMG solver: temperature Stabilizing uds-3 to enhance linear solver robustness.

      Stabilizing uds-3 using GMRES to enhance linear solver robustness.

      What is your mesh quality? (Max Skewness and Min Orthogonal quality) Please check if you have a good mesh to start with? 

      Also, are you able to compile your UDF without any errors?
