[mesh manipulation] Moving Mesh

mehdi.en · May 5, 2015, 10:03

Dear Foamers;
I am going to simulate deformation of a rubber pipe when a newtonian fluid (water) is flowing through. The pipe is considered viscoelastic. I want to know how could I create mesh (is the movingMesh utility appropriate?) and what type of mesh shall I use (is the movingMesh ok? Or I should use a meshless approach?)? What boundary conditions should I use? Which type of applications is the best for this problem?
Thanks in advance
Mehdi

Well Dear Mehdi,

You have asked a very general question! You have to be very more specific about what you are doing and what exactly is the geometry of your problem.
Your problem is a FSI problem and not actually very easy to get over with. First of all you have to have a good understanding of OpenFOAM FSI solvers, try solving some simple tutorials and then may try it on your own problem. You may take a look at this video:

Best.
