Fluent is freezing out in Unix based cluster
I am recently having problems using fluent in a Unix based cluster. The problem is the following: I load the modules of ANSYS and start fluent using the GUI interface (I have tried to open it in parallel and serial). Then, I try to read a file by clicking in the tab File->Read. Then, I select the file that I want to open. What happen after that, is that fluent is freeze out. Previously, fluent started to show commands in the console as fluent was reading the files. Now it seems fluent is not doing anything. I have left the program run for hours to see if this was a matter of time but still didn't work.
Another strange thing that is happening to me is that, if a click on File->Read and then just cancel this, again fluent is freezing out and then I cannot do anything else in fluent. No clicks in the GUI or type something in the console.
We have tried several things with the ITaP people in my university and it seems that is only with my account. I have opened some files in my local office computer and it worked, but in the cluster is not working.
Does someone know what is happening?
