I was running a fluent natural convection simulation with a time step of 0.5 seconds and everything was going fine until i decided to increase to 0.7s then there was a divergence in the solution until it crashed. I've been on this simulation for the past 2 days and I can't afford to restart the simulation. I have just the case (.cas) file for the last time step saved and the CFD post compatible data file (.cdat) extension. Is it possible to restart the simulation from the last saved timestep using these files?
Thanks.
Hallo Obiajulu,
yes you can use your last saved case as a restart file.
please have a look on the following link

I hope that might help
Best regards

hi, Obiajulu Nnaemeka,
Simulation can be resume from last saved files without initialize the case again. I mean, just reopen your simulation and do not initialize, direct click on " Calculate".
Good Luck
The mistake was from me. I did not specify the autosave setting for the data file. From what I read, the data file and case file is needed to continue. I just saved the case files which contains the boundary conditions and geometry, but not simulation data. After the simulation crashed I thought it was a good idea to exit without saving any changes when prompted, but apparently it wasn't. Saving changes create a new case and data file before exiting fluent. It was unfortunate I had to resume the simulation all over but it was also a learning experience for me.
Thanks for the help Mohamed and Muhammad!
