Hi everybody,
I want to solve the laminar flow physic interface in a geometry. The movement of some points on the boundary is specified and the movement of other points on the boundary should be interpolated. My issue is applying this movement to the model.
For simplification, I considered a cylinder geometry and I apply a simple sinus movement to a point on the boundary.
I used three physic interfaces: 1. laminar flow, 2. Shell & 3. moving mesh. In this case, the problem was laminar flow and shell physics were solved separately. So the boundary of the laminar flow domain was fixed during the time and only the shell was moved.
I think if I can use FSI physics, the problem of correlating the movement of the boundary to the laminar flow domain will be solved. But I don't know how I can define shell in FSI physic interface.
The file is attached.
I would be appreciated if anyone helps me possibly.
Dear Samin Haeri,
You can use FSI to achieve what you want. try this modified model to get the basic idea. I used a stationary solver and it worked. I deleted the solutions to reduce the file size.
Good luck.
Thank you so much, Marwan Nafea!
I upgraded my software from COMSOL 5.2 to COMSOL 5.4 to open your attached file & I found this new version has fluid-shell interaction interface.
