Hello everyone!
Iím dealing with changing of wall profile due to flow properties. The profile isnít known beforehand, so itís part of solution. Water flows in tube, the problem is planar. View of .cas file is attached. Mesh view in general and zoomed in deforming region are also attached.
The desired wall profile is taken from the article and picture is attached.
To my mind, wall deformation can be estimated according with Wall Shear variable.
So, Iíve got several questions.
1. Is it possible to solve such type of wall deformation, using CFX only (I mean, mesh deformation laws and UDFs)?
2. If not, then maybe FLUENT can do it?
3. If neither CFX nor FLUENT canít do this by their own means, then is the two-way FSI proper decision?
4. Is it possible to estimate contribution of each component of Wall Shear variable in common deformation? (probable functions that I use to deform mesh are attached)

Thanks a lot for help! )
