Dear All,

I am modeling a longitudinally expanding 3-dimensional duct with dynamic mesh. As the moving wall (rigid body) follows its path, the mesh expands, but the side walls do not deform smoothly.
The expanded mesh has rough, coarse walls. This becomes a problem in the simulation - the coarse walls act as obstacles and produce flow disruptions. I need to correct this.


Thank you for your help.
