Hello, I encountered a strange problem concerning the convergence of SNES.
In my recent test runs I found that SNES always stops at iteration 0... At first I thought there may be an error with the tolerance setting, so I output the tolerances : *atol = 0.000000, rtol = 0.000000, stol = 0.000000, maxit = 50, maxf = 10000 Norm of error 760.491 Iterations 0* Which are exactly the default values that I always used. However, for the same tolerance settings, the SNES solver converges successfully if I decrease the number of degrees of freedom in my system... I wish to know if anyone has experienced the same type of problems or has an idea about what could possibly cause the problem... Thank you so much in advance. I appreciate any advice that you provide.
