Scripting batch simulation in MEL

[catchyid]

hi,

I want to run multiple simulations sequentially, i.e. one after another, however I cannot find a way to do that in MEL script. Obviously, the MEL command "fumeFXcmd -runSimulation simMode fume;" spawns a simulation thread and returns control to the caller and I cannot find a function to tell whether the spawned fumeFX simulation thread has been completed or not. What I wish I had is either: (1) a fumeFX callback that tells me : I am done simulation (so I am ready to run another simulation, or maybe start rendering...), OR (2) a fumeFX function that tests whether a simulation job has completed or not.

Without having this functionality, I have to set in front of my PC and wait for one sim to finish, then start the other one manually...

Thanks in advance,

Hello,

Actually, there is a possibility to do so.
You could set some flag on the "PostSim" or "ffx_mel_PostSim" event.
I hope this helps.

Thanks for your reply. I have two fumeFX grids, let's say A and B, I have modified A script such as:

proc ffx_mel_PostSim( string $node )
{
fumeFXcmd -runSimulation 0 trunk_p2a_g1Shape1;
}

so, basically in A postSim event, I try to start B simulation, however this did not work and I got an error message : //Error: (FumeFX) Simulation already running!

I think, during these functions, FumeFX is considered running, so it won't start another sim, is this correct? If so, any idea how to overcome this issue?

Hello,

You can do it like this:

proc ffx_mel_PostSim( string $node )
{
evalDeferred("pause -sec 10;fumeFXcmd -runSimulation 0 \"trunk_p2a_g1Shape1\";");
}


It will wait 10 seconds after it's done to allow first FumeFX to finish everything and then it'll start simming the other FumeFX.

I hope this helps.
