Hi,
I would like to solve a PDE on a 2D grid for a single variable in Multiphysics under the constraint that the integral of this variable on this domain be some constant.
I have looked into how to do this in multiphysics and while the option seems to be available I can't for the life of me understand how to get it to work.
Is this possible? Could someone help me in the implementation please?
thanks in advance
