Hi Barry, this is it!
I changed our call to MatConvert to use MAT_INPLACE_MATRIX and it now works where MAT_REUSE_MATRIX worked before...
I am testing all the 34 test cases that were bugging with this to see if it make all the tests working again!
Thanks again to both of you for the super-rapid answers!!! :) Eric On 16/12/16 08:50 AM, Barry Smith wrote:
Eric, Perhaps you should be using MAT_INPLACE_MATRIX? The documentation is not as clear as it should be on MAT_INPLACE_MATRIX vs MAT_REUSE_MATRIX and it is possible that some implementations of MatConvert_xxx() are broken and do not use this flag properly. MAT_INPLACE_MATRIX means replace the input matrix with the matrix of the new type MAT_REUSE_MATRIX means reuse the matrix that has been passed in as the final value (that matrix must have come from a previous call to MatConvert() with the flag MAT_INITIAL_MATRIX) BarryOn Dec 16, 2016, at 7:43 AM, Stefano Zampini <[email protected]> wrote: Actually, the matrix type has not yet been set (since you have "null" in your output) 2016-12-16 16:43 GMT+03:00 Stefano Zampini <[email protected]>: Looking at lines 113-115 of master if (reuse == MAT_REUSE_MATRIX) { ierr = PetscObjectTypeCompare((PetscObject)*newmat,MATSEQDENSE,&isseqdense);CHKERRQ(ierr); if (!isseqdense) SETERRQ1(PetscObjectComm((PetscObject)*newmat),PETSC_ERR_USER,"Cannot reuse matrix of type %s",((PetscObject)(*newmat))->type); } you are trying to call MatConvert with the reuse flag on a matrix which is not of type SeqDense. Can you provide a MWE to reproduce the problem?
