[FLASH-USERS] Running multiple simulations simultaneously

[Ji, Suoqing]

Hi Malia,

Yes — you could simply specify different object directories by adding -objdir=YOUR_DIRNAME during setup, and compile your code under YOUR_DIRNAME.

If all of your source code remains unchanged for these variations (or in other words, you do not need to recompile your code to switch to a different variation), you could simply copy the flash4 executable, flash.par file, as well as all data files needed (including your grid data file) under any directory, and run your code from there.

Best wishes,

I am trying to run three variations of the same simulation. I can setup and run each of them individually, but if I run the setup script a second time (for the second simulation) it causes the previous simulation to no longer work. The setup script and almost all of the files used are the same for each simulation the differences are in the flash.par file and the initialization grid data. I have been trying to run the setup to have 3 work directories (one for each version). Is there a way to be able to do this?
I am running FLASH4.4
