Re: [Libmesh-users] "Unknown convergence flag!"

Well, getting the string from the originator of the code may not be a bad idea but once you get a code that does not make sense any more calls may be a concern although sure mostly it is version problems. I thought printing the int would be no effort and no risk. If you know what solver you

[Libmesh-users] Serialization and evaluation of all nodes in the master

Hi It seems I'm doing something terribly wrong. I need to run the system solution in parallel and then show the results in a GUI (master process). This is what I did: System & sys = equation_systems.add_system ("Poisson"); ... sys.solve(); if ( mesh.processor_id() == 0) {

Re: [Libmesh-users] "Unknown convergence flag!"

It took me a while to get back to this as it was not originally a big issue. AFAICT the libmesh method is translating codes from possibly many sources or solvers into something consistent for libmesh users. This seems to be a common problem- needing something efficient like int return codes
