Hello guys,

I tried implementing a valve opening/closing simulation inside a pipe using Fluent,

With 2D models, UDF and dynamic mesh are fine.

When using it on a 3D model, the cylindrical shape of the tube causes the moving wall geometry to change, resulting in a negative cell volume error.

How can I fix this?


p/s: I've attached the Geometries both 2D and 3D model
