[Libmesh-users] residual of solving Ax=b too big!

Hi all, I ran a larger case: with elements = 200, and found for each calculation in the iteration, system.final_linear_residual() is about 0.5%. 1) Is the system.final_linear_residual() r = b -A X* (X* is the solution) ? right? 2) It seems final residual is too big, and the equation is not solve

[Libmesh-users] makefile for libmesh 0.9.3

Hi all, Recently, I switched from libmesh-0.8.0 to libmesh 0.9.3, and found Make.common-based way in 0.8.0 did not work for 0.9.3. Is there example/instruction on writing a Makefile for libmesh 0.9.3, if one wants to include new codes? Thanks -
