<div dir="ltr">Hi all,<div><br></div><div>Are there any changes on the PETSc direct solver interface, for example, with superLU_dist and MUMPS. I found that my libMesh code failed with both of them, but still works with iterative solver (GMRES by default). Thanks a lot.</div><div><br></div><div>Best,</div><div>Xujun<br><div><br></div><div>--------------------------------------------------------------------------------------------------------------</div><div>
