FSI fluid structure interaction tutorial chapter 23
 

Hello all,

I'm trying to follow the chapter 23 of the tutorial that comes with CFX (anys 12), but it won't give me any solutions. The error is that the solver stops. Does anyone have the working workbench files so i can try to compare mine?

Thanks.

New info
 

I'm all done with the configuration, but the solver is saying i have an error. PLease help!!!

This is the info that i get:

Hi,

When a tutorial does not work 99% of the time it is because you missed something. Go through it again carefully and make sure you don't miss anything.

i got it to work
 

Thanks Glenn. I got it to work by changing the default mesh (cfx by the automatic one) that was the only change. Anyways, when i try to post process it, it gives me this image

but i believe the wall should be a lot smaller that what is shown on the pic. How can i make the fluid and the wall the same scale? (wall vertical square, fluid small horizantal square, please refer to tutorial 23 wb 12)


Thanks.
