Dear all,
Does anyone know how to post process simulation outputs with command line?
I build svSolver on my Cluster, and I found that svpre, svpost and svsolver were provided in /svSolver/build/svSolver-build/bin.
I was wondering that if we can use svpost to process files in command directly without GUI. What arguments should I give to svpost?
Regards,
Yikai Kan

Re: Post processing with command line in linux
Hi Yikai,
Thank you for your question! You certainly can run svpost from the command line. You can check the input arguments by running svpost with the '-h' flag. But briefly, you will likely want to include the following flags:
-start X: starting step number for post-processing
-stop Y: last step number for post-processing
-incr Z: increment of files to post-process. Typically best to set this equal to the "Number of timesteps between restarts" option in solver.inp
-vtu [name]: indicates the name for the .vtu (volumetric) output file
-vtp [name]: indicates name for the .vtp (surface) output file
-vtkcombo: aggregates all results from all timesteps into single files. This will also enable computation of time-averaged quantities like time-averaged wall shear stress and OSI. Note that if you indicate step 0 as your starting timestep, the time-averaged quantities will not be output since the wall shear stress is not defined at step 0.
Additional options for post-processing can be found by running it with the -h flag. Hope that helps!
