Hi Christophe, On a slightly related topic: where do you use PETSc specifically inside Gmsh ? I haven't looked at the sources in a while but was curious. I will configure the latest source based on PETSc soon to understand the details. Any help/pointers will be much appreciated.
Hi Vijay, Gmsh uses Petsc i.e. for STL remeshing , see https://geuz.org/trac/gmsh/wiki/STLRemeshing Regards, Dave -- David Colignon, Ph.D. Collaborateur Logistique du F.R.S.-FNRS CÉCI - Consortium des Équipements de Calcul Intensif ACE - Applied & Computational Electromagnetics Sart-Tilman B28 Université de Liège 4000 Liège - BELGIQUE Tél: +32 (0)4 366 37 32 Fax: +32 (0)4 366 29 10 WWW: http://www.ceci-hpc.be/ Agenda: http://www.google.com/calendar/embed?src=david.colignon%40gmail.com
