Re: [deal.II] catching SolverControl::NoConvergence

Is there any redirection to another solver? Is this a potential source of the unexpected behavior mentioned above? Good question. Can you create a minimal test case for that as well?

Re: [deal.II] ERROR WHEN RUNNING THE CODE ON MULTIPLE NODES OF HPC
On 8/2/20 11:26 PM, 孙翔 wrote: Yes, it cannot run on a cluster. Both of them run in release mode. I'm also curious about the error. I debug the code by outputting some specific values. If you see any error, the first step always should be to run in debug mode instead. Make sure that that works, and only then is it worth your time to think about release mode!
