I am getting this error while computing. Please help me with this

In Segregated Step 1: There was an error message from the linear solver. The relative error (0.004) is greater than the relative tolerance.

Hello Himanshi,

Without the context provided by the model, it's not possible to diagnose the cause of this error message with any kind of certainty (Obviously, the solver didn't converge, but we can't tell why without seeing the model, and we couldn't make recommendations for how to fix the issue with both seeing the model and knowing what exact physical situation you are trying to model). Please consider uploading your .mph file (with the mesh and solution cleared if need be to keep the file small) and posting a description of what you are trying to model.

Best,

Jeff
