fluid-solid coupling

[王艺康]

Hello, 

        I would like to ask a question, I would like to combine STEP-18 and STEP-35, or I would like to realise unidirectional fluid-solid coupling, where the fluid flows through the interior of the model, and given the equations of motion for the walls of the model (contraction, diastole at a fixed velocity), how do I go about achieving such a result?

At the end of the day, you will need to start by defining exactly the
set of equations you want to solve. This is not clear to me from your
post above, but once you have the equations that describe your model,
you can start thinking about how to implement them.

There are numerous questions and answers on this forum regarding
fluid-structure interaction problems. You might also want to look
through the list of publications at

to see what others have done and how they have done that.
