Dear petsc developers. Hello. While I was applying the preconditioner in contact with the FEM code, I had some questions.
How can I apply the AMG PC and the multilevel Schwarz PC in the FEM code? Purpose is to compare which PC is better in the FEM code with contact situation. In my case, the Jacobi PC could be easily applied as shown in the example below. However, AMG and multilevel have too many options. ex) ./app -ksp_type gmres -pc_type jacobi -ksp_view Best regards Seung Lee Kwon -- Seung Lee Kwon, Ph.D.Candidate Aerospace Structures and Materials Laboratory Department of Mechanical and Aerospace Engineering Seoul National University Building 300 Rm 503, Gwanak-ro 1, Gwanak-gu, Seoul, South Korea, 08826 E-mail : ksl7...@snu.ac.kr Office : +82-2-880-7389 C.
