Greetings everyone,

I am using TRNSYS and genopt for optimizing the life cycle cost of solar combisystem. My optimization ends up after 5 mins with following error. Your help is highly appreciated.

genopt.lang.OptimizerException: 
File: 'C:\Users\User\Desktop\WithAL\tmp-genopt-run-1\hereforerror' does not exist after simulation call.

hereforerror is the file name of the log/lst file. Here I purposedly did not mention the extension such as .lst or .log because when I tried with those extensions as well, it showed same error. I would greatly appreciate anyone's help as I am approaching the deadline to present my paper soon.
