Dear all,

I work in a 3d vof problem with solid cylinders. When i upload in Fluent i get these ..(shown below).

Why this occur?I have used shared topology in design modeler.

Can any one help.

Thanks

Hello,

If you are using Sliding Mesh type of analysis, please do not use Share Topology between bodies which are sliding about an interface. Instead, ensure that your have created contact regions (in Meshing). Please see if this helps.

Thanks. 

Best,

Thanks for the response Karthik, My problem is a open channel flow past a vertical cylinder and my mesh does not slide. 

I don't know why such info comes. May be i will try with contact regions. Thanks.
