OpenStudio Increasing Load Convergence [closed]
Having troubles with my model and believe the run time is being increased by the errors that are being written. Is there any way in OpenStudio to increase the "Load Convergence Tolerance Value"? It seems that when I increase it the value didn't actually increase.

I would expect the tolerance value to increase from .1% because I have changed the "Load Convergence Tolerance Value" in simulation settings multiple times with no change. Any pointers towards what I can do to slightly increase this value would be awesome.
I did confirm that we write "Load Convergence Tolerance Value" To the "OS:SimulationControl" object in the OSM file (if you change the default value) and that in turn is written to the "Building" object in the IDF. You may want to confirm the value in your IDF. There may be another tolerance setting that relates to your error?
