parsing error of section OUTFALLS when name of time series exceeds 10 characters

[laltuashu]

Hello all,
When I run the model using parallel mode in DEoptim, the error is as given as below
"Error in checkForRemoteErrors(val) : 4 nodes produced errors; first error: cannot coerce class 'c("xts", "zoo")' to a data.frame".

,But when I run the model without parallel mode in DEoptim, I got the errors as below

Error in [.xts(x, , 2) : subscript out of bounds
In addition: Warning messages:
1: In normalizePath(path.expand(path), winslash, mustWork) :
path[1]="C:/Users/ratnakar/AppData/Local/Temp/RtmpkNMgOy/fileca41c942dd9.out": The system cannot find the file specified
2: In read_out(file = swmm_files$out, iType = 1, object_name = "621", :
error reading out file

Any suggestions in this regard will be highly appreciated.

Regards,
Ashu

@laltuashu I'm able to reproduce the error. A quick fix would be to limit the length of the name of your outfall time series to 10 characters, i.e. "outfall_timeseries1" becomes "outfall_ti".

Hello @dleutnant Sir,
Thank you for the guidance. The error is resolved now, but the simulation time is too high.
Is there any way to increase the speed of calibration execution?

You could 1) modify your model structure and setup (model size, time steps, simulation duration, etc.) with respect to your modeling objective and/or 2) use more computational resources if the algorithm supports parallel execution.

...of course the choice of optimization algorithm also might improve your calibration efficiency.

Thank you sir for your suggestion.
I will certainly try ways to reduce simulation time.
