Description
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,

Research direction
Start with examples/prom/nonlinear_elasticity_global_rom.cpp and the MFEM ConvectionIntegrator documentation referenced in the issue. Work out whether that integrator represents the nonlinear term div(alpha u grad u), and document or implement the appropriate ParNonlinearForm approach; done means the formulation is confirmed for the stated heat-conduction equation.
