couldn't find the cst.file in CFD post folder
 

Hello,

When i was trying to open up the CFD post to do some post-processing, i got a warning says that the cst.file is not existed or cannot be opened.
I look up into the CFD post folder, which has nothing there. Like usually, Fluent will automatically generate a cst.file, and save it inside the CFD folder once the simulation is done.But now, something went wrong with the fluent...
Does anyone know the reason behind it?

P.S. I am using Ansys Fluent 16.0.

Thanks!
