Hello all,

I must to simulate a 2D mini regenerator in Fluent. But I don't have sufficient experience bucause of this I need your valuable advices ,I'll be glad if you can help me.

Problem is follow;

Regenerator has reciprocating motion on x direction. It has 2 mm
stroke and it should move at 60Hz on x direction, additionally it take place
a porous media.

Firstly, I need a UDF that corresponding my problem (about reciprocating motion).
p.s. :I checked many studies and articles but I could not find convenient answers.

Secondly, When I searched the literature, I found the following code to turn on recirculation inlet, outlet boundary conditions in Fluent. But I could not implement that code to Fluent how can I do it:
