APDL Matrix Equation for a FSI system with mean flow effect

      Hello,

      I am working on Ansys APDL for a FSI model and I apply mean flow. I would like to know if someone has the Matrix Equation including the mean flow effect ? I can only find it for coupled acoustic fluid-structural system without the mean flow

      Hi

       

      I do not think that is possible.

       

      Perhaps see the book of M. P. Paidoussis, and the FE formulation of fluid conveying pipe elements (they could go into a MATRIX27). E.g.:

      Stack C., Garnett R., Pawlas G., A Finite Element for the Vibration Analysis of a Fluid-conveying Timoshenko
