AMG troubles - help?
I started a parallel calculation with AMG. After 60 iterations the job is killed. Error message is following:
Process 1 amg_error: amg_trunc : error (1) occurred ierr_amg= 2981 Please contact CD-adapco support. STAR MPI_ABORT executed from processor 1
For an another mesh (same geometry ans settings) the job run until convergence.
What is the problem?
Thanks for your help.
Re: AMG troubles - help?
try CG algorithm. If it works, it means the AMG solver diverges.
