My IT department recently updated my ArcGIS to 10.3 and InfoWater to Suite 11.5, Update #5.

When I ran my potable water model, which had been running without warning previously, every VFD pump had an error which stopped the Extended Period Simulation. I have been able to get the model to run by changing the pumps to run based on hydro-pneumatic tank levels, but it does not reflect the actual state of our system.

Has anybody else had an issue with VFD pumps after update or is this a problem known to Innovyze?
