Periodic Zone and Dynamic Mesh

vasava · August 20, 2013, 03:01

I am trying to simulate a periodic zone including dynamic mesh.

There is a sphere moving through a cube. The motion of sphere should be periodic so when one sphere leaves from right face another sphere must enter from the left face. I have declared the left and right walls as periodic. But as the sphere reaches right wall I receive 'negative volume' error.

What do you think is missing?

I managed to solve the problem with the mixing plane approach. But it would be nice to see comments with people who have had or solved such problems.

Dear vasava,

can you explain more how you managed to solve the problem? have you used periodic boundary condition? I would really really appreciate it if you could explain more about your solution. thanks

I'm also interested in the solution.
I had a similar problem of a water pool where some boxes enter/exit and reenter, but I didn't found a solution.
