<div dir="ltr">Hello, <div><br></div><div>I am just learning to use GetDP as I have adopted some code, and would very much appreciate a few pointers on the solver options! <br><br></div><div>
According to the manual, GetDP uses linear solvers from PETSc by default, and I can change solver options/parameters in the command lines or .petscrc file. I have a few questions about this: </div><div><br></div><div></div><div>1) I ran a simple electrostatic model and it showed, "preonly lu mumps" during processing, I think, that meant the direct LU solver from MUMPS was used? Is this the default solver option within PETSc? <br></div><div><br></div><div>
2)
How I can find the default tolerance settings? Oddly I can't seem to find a .petscrc file within my directories...
I am using the precompiled GetDP 3.0 version download from the website.
