Fsi ansys cfx?

Mostafa.T · November 11, 2009, 10:39

My problem is: Soving a transient flow in a straight and elastic tube.(fully developed velocity profile at inlet and pressure at outlet are my boundary conditions)
I follow all the steps which are included in the help, but I face a error message when I want to solve. It says you should refine your mesh in solid domain? how can I do that? Should I use an external mesh generator?
If it is possible please tell me about this problem expressively. Further, how can I find the discretized equations

of the ANSYS CFX (both solid and fluid sides)?

If you've installed ANSYS Workbench and CFX, you can try improving your mesh in ANSYS Workbench, and then import the Mesh into CFX. You can see this import option in the Project page. i've done this in version 11

Hi,
I wont to implement a full developed inlet in ANSYS CFX 12. I have the *.csv file, that CFX-pre read without errors, I've selected the correwct local coordinate frame and selected the profile from the list of profile boundary set up. The problem is: when I click "generate data" an then "apply" nothing happens.
Can anybody help me?

hi i have problem as same as you.

If you have only one coordinate frame you can simply untick the coordinate frame field in CF setup, boudary conditions, Basic settings and in your file don't write anything about Ref Coord Frame.
If you need more coordinate frame you have to define them both in CFX and in yous .csv file, choose the corect one in Basic setting and then you can check, using the plot option, if everything is ok! Good luck

i've got 1 coordinate frame. i checked coordinate frame option but nothing happened. without coordinate frame the situation was as same as before. the values didn't generate.
