[ICEM] Multi-Zone Sliding Mesh

JOKER · December 12, 2010, 19:59

Hello Everybody..!

I have been trying to simulate a 2D Flutter Excitation System (just for sliding mesh tutorial). Fluent did not read this mesh (Error : ACCESS VIOLATION).

i have made different zones by saving blocks in different parts and is applying wall BC to inner and outer boundaries of cylindrical portion.

My strategy is that inner block will slide with outer block: give me some suggestions..?

here are the images

After Meshing I realized it could be batter to model zones like this...here red lined edges are assigned with wall BC and white marked as interface BC..
..

I also realized that there is even no need of different parts so I merge these parts and also remove the interface condition from the edge(hit and try:thought this could be the problem)

About Meshing: I have made a simple CH topo about airfoil then split block at Cylinder airfoil intersection then 3 O-grid for cylinder and delete the airfoil block and put 3 manual blocks about airfoil (finding problem to insert C type split using O-grid)

Hy everybody i have sorted it out, actually when i edit edge one portion of the edge set free (that i have assigned to a line with BC, now half of the portion is set free and half being assigned).
