abc197 is on a distinguished road
Hi, I am really new in using Gambit and Fluent. I am dealing with a simple problem like this.

Will the geometry simply be drawn in usual manner for outer and inner rectangles (Drawing two blocks and subtarcting the smaller from larger one)and then just change the boundary conditions for the smaller one in fluent accordingly (translational in this case). Is it correct so far? This doesnt work actually, so can any one help me through this.
What if smaller one is actually a vertically oscillating circle. In the gambit portion, what options do I have. Also how to use dynamic mesh or sliding mesh in such problems(if necessary in this case). Kindly let me know if tutorials are available for these(Gambit or design modeler).
