Unexpected CFX_SOLVER license error in ANSYS-CFX FSI Simulation

PranjalNewton · May 22, 2016, 10:47

Hi there!

I am trying to run a simple 2-way FSI problem of flow through a flexible tube. The problem is that I can seamlessly run ANSYS and CFX parts separately but the FSI is not running. I have an academic license for separate and FSI both but FSI simulation is giving this error. The main problem I see is the error that CFX_SOLVER license expired the moment I ran the simulation. Which is not the case since I can run the uncoupled simulation fine just after that. I have about 55000 nodes in the model which is below the cap.

Please help!

contact your system/license admin of your school. To me, that seems more straight forward than letting us guess what might be the cause...

Lance · May 23, 2016, 03:37

The message:
The license CFX_SOLVER expired on 2016/05/22 19:09:45.
seem to indicate that your license for
ANSYS CFX Solver (Max 128K Nodes) + Parallel
has expired? Are you sure you still have a valid license? Have you tried to run in serial?

PranjalNewton · May 23, 2016, 05:29

Thanks for the replies everyone. Both the suggestions were helpful. The problem is solved. The multiphysics and some other licenses were being upgraded at that time so I was unable to run the simulation. Although I checked the licenses at that time... but don't know why they were showing available. This resulted in all the confusion!

Thanks again.

I am having the same problem, please tell me how to solve it.

i have same problem in transient simulation by ansys 14.5, this is error information, i copy cfx pre to other computer that the transient can run, ansys version is same ,but why?

The error message explains exactly what the problem is. It cannot check out a solver license. So somebody else has the license, you are not connected to the license server or the license has not been released properly from a previous run or you do not have that license.

hello I was tried to build FSI by using CFX with system coupling but the CFX does not connect with system couple I was tried by using to version 14.5 and 16

Can anyone give me some help?

ghorrocks · February 6, 2018, 17:43

There are lots of tutorials for FSI and system coupling, even for older versions of CFX, on the ANSYS Customer webpage. If you are a student and you cannot access that there is reduced number of tutorials on the ANSYS student webpage. So have a look there and do the tutorials.

This is the CFX-forum, whereas you use fluent. So ask your question in that forum.
And don't hijack someone else's post. Create a new one for your own.
