Hi
I believe so, you need to define how your "y" is reduced, that is is it simply dropped or do you integrate along y ?
this defines if you should us a linear or general Extrusion or Projection

Good luck

Thanks for replying. I didn't mean to do integration, what i meant is something like:
I have an equation involving u(x,y), but instead of using a stationary solver I reformulate the equation as something like u(x,t), where the variable y plays a similar role as t, and hence solvable using the time dependent solver in 1D model.
I have the other model, where i would need this variable u, but this time, it is a 2D model, non time dependent. This is why i need to convert u(x,t) back to its original form, u(x,y). Is it possible to do this within GUI, or do i have to do it via MATLAB?
I apologize of my explanation sounds vague or ambiguous. I would try to clarify further if necessary.
Thanks in advance.

Hi
indeed I do not believe I really understand what you intend to do. But finally COMSOL basics is a PDE solver tool for a given subset of useful functions, of the type used for common physics (that fits in the global or coefficient form. Then the naming and differentiation between time and spatial variables is basically a convention issue, the math behind does not really change
