Running Multiple Simulations from Workbench 12.1
 

Hello all -

I have multiple licenses available from CFX. I am using a separate license for each application so that I can run multiple applications at once from Workbench 12.1. Currently, I have a Workbench project with two different simulations (A and B). I can open several instances of CFD-Pre, -Post, and ICEM, as desired. However, I cannot seem to open up anything new once a simulation is running in Solver. For example, when I'm running simulation A in Solver, nothing happens when I double-click CFD-Pre in simulation B. My mouse indicates a busy signal (hourglass) and I cannot open anything while a simulation is running.

Is it possible to run multiple simulations simultaneously from Workbench? I know you can outside of Workbench, but I enjoy using Workbench.

Thanks!

hi,
maybe this might help:
right click above the solution branch --> switch active task to background.

Thanks for the response, Neewbie.

I was able to open two solvers at once (one each for simulations A and B). I ran A, then attempted to run B. A ran successfully, but B turned up a licensing error.

I know I have 5 licenses available for use. I see them on the server utility and I'm able to open 5 instances of any CFX program. However, it doesn't seem to allow me to actually run 2 simulations from the same Workbench project at the same time.

Do you think I could fix the problem by having two separate Workbench files rather than one Workbench file with two simulations on it? Is it hopeless to run two simulations simultaneously in Workbench?

I have fixed the problem, but I don't know how I did it. Neewbie's suggestion allowed me to open two simulations, though the first time I tried running them both in parallel, I received a licensing error. This time, I ran one in parallel, one in serial, and it worked. Not sure why. I have 5 licenses.

Thanks!
