I'm getting the following error when using GAMG. petsc-dev/src/ksp/pc/impls/gamg/agg.c:508: smoothAggs: Assertion `sgid==-1' failed.
When I try to alter the type of aggregation at the command line using -pc_gamg_type pa, I'm getting [0]PETSC ERROR: [1]PETSC ERROR: --------------------- Error Message ------------------------------------ [1]PETSC ERROR: Unknown type. Check for miss-spelling or missing external package needed for type: see http://www.mcs.anl.gov/petsc/documentation/installation.html#external! [1]PETSC ERROR: Unknown GAMG type pa given! Has there been a change in the aggregation options? I just pulled petsc-dev this morning. John -------------- next part -------------- An HTML attachment was scrubbed...
