Hello,

you can further debug the timings with "-d=execstat", this enabled debug flag execstat, that dumps the time spend in each module.
Based on that analysis it's probably possible to change the configuration, so that the compiler performs better.

so long.

Thanks you

I tried to -d=execstat for the model.
And then following is result of high percentage commands.

If it's large nonlinear equations, performance should be expected to be slow in the backend. It means many equations are related to each other, which means any sort of dependency analysis or change in an equation will affect many other equations. What can sometimes improve performance is if common subexpression elimination can move parts of the nonlinear system outside of the algebraic loop. You can try it with some of: --preOptModules+=introduceDerAlias --postOptModules+=wrapFunctionCalls.

Otherwise, sending the model to us via a ticket (or openmodelica@ida.liu.se, or directly to a developer encrypted if it's sensitive information) and we could perform a more detailed profiling of the model and see if any support function can be improved to get better performance for some detail in the model.

Thanks sjoelund.se

I tried options  for the model in OMShell.

setCommandLineOptions("--preOptModules+=introduceDerAlias")

setCommandLineOptions("--postOptModules+=wrapFunctionCalls")

And following is Result.
