Ata, system.solve() will call it. I assume that by "changing constantly" you mean "once per timestep"? SNESSolve() initiates the call that eventually dispatches to your bounds calculation routine. SNES calls that once per solve. Dmitry. On Wed, May 9, 2012 at 5:22 PM, Ataollah Mesgarnejad wrote:

Dmitry, A quick question: When does the bounds routine get called? My bounds are changing constantly do I need to call the bounds function myself or does it get called for each system.solve()? Thanks, Ata On May 5, 2012, at 12:21 PM, Dmitry Karpeev wrote: > Okay, that helps. > I'm looking fu

Dear all, I use ExodusII_IO::write_timestep for my programs output into a single file for all time steps. When I do an adaptive refinement is it possible to update the mesh in the ExodusII file? Is there a flag I can pass or can I call a member function in ExodusII_IO? More generally is it eve
