dynamic mesh test of a cube fails
I try to test a dynamic mesh motion in order to get setup information for a much bigger simulation.
For the test I use some cubes with a surround small volume in order to keep the quality of the mesh. I donīt really know wich dynamic zones have to be created. Can someone show some examples?
I also have problems with the remehing tool of fluent. I tried a lot an I describe you my errors.
1. The small volume moves but the interface is switched to a wall and the volumes are not coupled. Fluent gives this note:
"Note: zone-surface: cannot create surface from sliding interface zone. Creating empty surface."
2. The small volume and the big volume are coupled but I get negative cell volume. I tried to reduce timespteps and changed the remesh setting, but everytime after 0.15s it is over.
I post you some pics.
Thanks for your help.
