Sorry for this late reply.
There is no singular system detection in PaStiX since we use a static pivoting strategy.
But we provide as output the number of static pivots that have been found during the factorization that indicates if the solver could failed or should be used as a preconditioner with the internal refinement step.
Best regards,
Pierre.

Hi,

Is there a way to detect if the system to solve is singular ?
I'm currently using the version 4030

Thank's in advance.
