HI, dear dealII users and supporters, I am a very new user of dealII and knows very little about C++.
I started everything from the step-31, Stokes equations solving vector field 'u' and scalar field 'p', and a temperature equation for 'T'. My problem is similar to this, namely I have a scalar field, say 'C', 'C' is an explicit function of 'u' and 'p' (for example C=(\nabla u : \nabla u) - p ), so i don't need to use fem to solve for 'C' like the example 31 solving for 'T'. 'C' can be directly expression by 'u' and 'p'. I would like to use 'C' a lot as intermediate variable (for example to help define the volume force of the momentum equations), so I need to know 'C' at every quadrature points. I also want to export 'C' in the .vtk output. My question is what be the most reasonable or efficient way to define and calculate such 'C'. Do I need to define 'C' as a solution variable, exactly like 'T' even I don't really need to solve for it?
