I get the following error when i run the calculation. I am using PEMFC model in ansys fluent. I followed all the tutorial steps. When i run the calculation I got the following error and application crashed.

I am using academic version of ANSYS.

I assume that file exists?

[Ravivarma2012]

yes. the file exists. 

the following error is displayed before fluent crashes as shown in screenshot below:

mpt_accept: error acept failed: no such file or directory

[Ravivarma2012]

Now I get the following error. I have redone the geometry and mesh. Defined the models in fluent as per the tutorial steps. When I run the calculation fluent crashes with the following error:

Can you try from a path without spaces in the name? Shouldn't be an issue, but may depend on how the commands are stored in the code.

Not sure. Check available RAM (and try in serial) then I think you'll need to ask your supervisor to log a support ticket. We're not able to review files on here (export law) but can assist staff from client Universities.
