Integrator for non-linear term #199

Open gokhalen opened 1 year ago

gokhalen commented 1 year ago

I'm trying to build a FOM for the non-linear heat conduction equation i.e. heat conduction equation in which the conductivity K depends on temperature. i.e. K = k0 + \alpha u where u is the temperature. Since I want it to be as close as possible to the nonlinear_elasticity_global_rom.cpp, I'd like to use a ParNonlinearForm for the term \div { \alpha u \grad u}. Is the ConvectionIntegrator the right one to use for this purpose?

Thanks,

-Nachiket

Hi Nachiket,

MFEM example 16p may be helpful as a starting point:
