Bruno,
another option is to just pack all of your variables into one FESystem and
DoFHandler, and solve the linear systems related to each variable one at a
time. That's basically the difference between step-31 and step-32: The former
has two DoFHandlers, one for the flow variables and one for
Dear Daniel,
I understand, it perfectly makes sense.
I had not thought about using two different FEValues when looping over the
cells.
Thank you very much!
Best
Bruno

Dear Daniel,
I am sorry, my question truly was unclear.
Let's say I solve a first equation for Velocity, and I would like to use
this velocity in another equation for advection-diffusion of say
Temperature.
I would first set-up my DOF and FE system for my velocity equation and
solve it and set-u
Bruno,
Hello everyone, I hope you are well.
