Siamak,

In fluent, you have the possibility to “autosave case and data files” at a given frequency. It is also possibLe to create transient animations but I believe that Fluent is weak in terms of post processing.

If you want to make good quality video animations, I recommend you to export the Fluent data to ParaView in Ensight format. The post processing of unsteady simulations is much better with Paraview.

Regards

Thank you Mounir! You are right the post-processing in FLUENT sometimes gets really complicated! However, I found the solution. One can define the desired variable in the "custom field function" and then, selected in the "sampling options" in the "run" page.

Dear Siamak,

While doing this, please remember to click on "Reset Statistics" in the INITIALIZATION box before RUN the case.

Good Luck

Good point Muhammad. Thanks for your help.
