Elmer Discussion Forum

Hello, I'm trying to do an inversion to adjust the friction coefficient using the Discrete Cost Solver. The problem is that after iterations I get the following error:

ERROR:: IterSolve: Numerical Error: System diverged over maximum tolerance.

This is during nonlinear iterations as you can see in the file attached (errorlog.txt also sif file), I even tried changing the Nonlinear System Convergence Tolerance to 1.0e-1 but I still recieve the same error

Any suggestion?

Hello,

After downloading the rar archive, and looking at the files, would it be possible for you to:

1. post the full log output from elmersolver.
2. post the mesh files. The forum will accept files up to 1 Megabyte in size and up to three attachments per post.

With the mesh files and a working sif file, then others will be able to recreate your example.

Thanks, Rich.

Hi, I uploaded the log and mesh files in the new rar but I can't upload all the data for the size, in this link you will find everything
