How can we consider time derivatives in the source f coefficient in the pdetool system method?

1 view (last 30 days)
I use pdetool in 2D to solve a partiel differentiel a set of equations (4 equations). But I have to introduce in the f coefficient (fcoeffunction(region,state)) corresponding to one solution component a term which depends on the time derivative of another solution component. But state.ut(i,:) doesn't exist a priori.

Can you please be more specific? What is the system of PDE that you are trying to solve? Can you please explicitly state the equations? I believe you are trying to solve a non-linear equation - is that right?

The PDE toolbox does not support this type of dependency.
