Hi all,
Instead of solving Ax=b, where, A is system.matrix; b is system.rhs, x is
the solutions.
I need to 1) assemble 2 system.rhs: b1 and b2;
2) solve A x1 =b1, A x2 =b2;
3) then obtain the final solution x = f(x1, x2);
I wonder how to do the above job. Could I have 2 rhs, solve the two
intermediate variables, and then obtain the final solution x? Or libmesh
has other built-in function for this.
Thanks,
Walter
