slow simulation

February 28, 2008, 00:23

i am sunning a simulation of a supersonic impinging jet using a grids 100*100. It takes 10 hours to get a non-dimensional time (t*Ve/D) of 25!!! Ve is the speed of sound at nozzle exit, D is exit diameter. is it just me or is this normal??

Hi! Shuo. It is too long time to run the compressible code. As far as I know, my code also takes such long computational time to reach that non-dimensional time. I guess that 10 hours is not severe.

Maybe I should break it into multi blocks and use parallel computers.
