Deforming Mesh in Fluent but Cells keep stretching!

Hi,
I'm trying to create a dynamic mesh in Fluent. It's basically a square that that increases with height. I have been getting problems with the deforming of the mesh. Basically, the mesh keeps stretching rather than create new cells everytime it increases in height. It is a tetrahedral mesh so i cant use the layering method. I disabled the smoothness option and kept it to the remeshing option in the gui. Can anybody help? i have attached a picture of my problem. Hope to get some reply soon. |

Hi,
What are the deforming conditions you imposed in the Dynamic mesh zone box? Are the side walls set to deforming and the moving wall Rigid Body ? |

the box (meshed as one entity) deforms as a rigid body and it's base is modelled as stationary.

Ok,
Maybe try to impose the following conditions on the surfaces : - moving wall : rigid body - opposite wall (to the moving one) : stationary - side walls : deforming (You don't need to impose any deforming condition on the box volume.) |

Hi there
Could you please explain how you resolved this problem. I've encountered something very similar in a 2D rectangular domain with a moving circle in middle (when the particle moves, mesh cells near the wall are getting stretched). Thanks |
