Reading wall shear stress at interface in Intrinsic FSI Fluent

[zahra.rahimimotlagh]

Dear all

I did a intrinsic FSI simulation in Fluent and I want to read Wall Shear Stress (WSS) at interface of the fluid and wall but I realized that Fluent does not read WSS at interface. Also, it does not show me y+ in this surface.

My geometry is a rectangular channel that a section of bottom wall is flexible wall. Compliant wall has a thickness of 16 mm so they are two rectangular channel (Fluid rectangular channel and compliant wall in bottom). surfaces at fluid and compliant wall are defined as interface.

I need to obtain WSS at this flexible wall.

I would be grateful if you could guide me about that.
