He residual of the MUMPS solver is 1.52e-04, which is above the maximum allowable value of 1.00e-05

It is harder and it takes longer to provide support without full details. To speed up the process and quickly solve your issues this is a reminder to post as much information as you possibly can:

Hi @pkaran thanks for posting on the forum :slight_smile:

Your model has many features that might make it difficult for simulation - and the generated mesh is really distorted. Look at the Aspect Ratio for instance:

To get around that, one possible workflow would be to apply some refinements to the mesh, as I’ve done in the following project:

In order to check and Improve the quality of your mesh, please take a look at the following article:

However, I’d advise you to make some simplifications to your CAD, since these refinements will make the mesh too large and consume lots of resources.

Does that help?
