Flexible Wall

sunilpatil · September 2, 2014, 11:21

Hello Sir,
I am interested to simulate flow over flexible aerofoil in Ansys CFX, but i am unable to find how to define wall as flexible. I am having the required equation to account wall flexibility.
I have searched lot in electronic media and most of them are used FSI (Fluid structure interaction). Is there any other way to model this problem without using FSI.

If you know how the wall will respond to the acting forces, write the equation here and someone may be able to guide you on how to do it using CEL in conjunction mesh deformation/motion.

Without the expression, it is nearly impossible for anyone to guess what the expression dependencies are, nor which variables are readily available for use.
