'while' control flow for large simulation sweep in maestro run plan

cdnspg over 2 years ago

Running large simulation sweep with multi-parameters

parm1 p1start:p1step:p1end

parm2 p2start:p2step:p2end

... or parm sweep.

I would like to break out of the simulation sweep triggered by a condition part of output of the same simulation analysis block. Something like a 'while' control flow

while(condition_in_sim_output, sweep_parm)

Simulate

with condition to be a pass/fail from a condition in outputs of the simulate block and having corresponding parm values meeting condition on-hand.

The purpose is to reduce the simulations in sweep as the condition can possibly be met early in the sweep.

Any way to implement this simulation flow thru a combination of ocean script code and Run Plan in maestro?

Thanks for helping

Since I don't know the details of the simulation set you are trying to perform nor what format of the output data you are hoping to generate, I can't provide a specific answer. Nonetheless, I have often performed sets of simulations whose number is dependent on a simulation result using an ocean script. Ocean supports the while() control structure:

Without using oceanXL commands, the output data from your ocean script will not be written into a format readable as an Assembler/Explorer session. If you wish to place the data into a format for Assembler/Explorer, your ocean script will need to include and be compatible with oceanXL.

Alternately, you might consider creating a run plan where the number of simulation corners of the second run is dependent on an initial run. There is an example of this methodology at URL:

I hope I understood your intent correctly and these provide some ideas to consider cdnspg!
