Hi, Dear all.
I recently tried to simulate pressure-driven stokes flow using CFD module.
In my study, I should calculate the flow behavior with cylindrical anisotropic viscosity.
So, the radial, azimuthal, and z-direction components of viscosity must be designated, separately.
ex) mu=[2 0 0 ; 0 1 0 ; 0 0 1] in matrix form
Unfortunately, dislike other physical modules, such as heat transfer (in attatched figure 'heat'), CFD module does not allow to use 'vector-form' anisotropic input variables (in attatched figure ' flow').
Could u suggest a good idea to solve this problem?
or recommend the other method to handle this?
I tried to build up stokes equation using 'coefficient PDE interface', but it is not easy to optimize and utilze the same as to results of CFD module..
Please help me with some advices.
Thank u for reading.
