[Libmesh-users] how to give variables non-zero initial values?

Hi all, I am following example 13 and trying to solve a set of nonlinear PDEs using the solver of libmesh. I have noted that: >From previous Newton iterate, the variable values of "u" and "v" can be assigned by u += phi[l][qp]*navier_stokes_system.current_solution (dof_indices_u[l]); v += phi[l][qp

Re: [Libmesh-users] VTKIO Clarification

Hi: I reverted back to 2D simulation and have been using the VTK_IO functionality somewhat successfully, but one thing I cannot figure out how to do is make sure each simulation file has a time associated with it. In Libmesh I update the equation system parameter "time" to reflect the valu
