"Peak Flow Rate" values do not "stick" after changed

Hello all

I´m trying to insert 80 liters per day DHW (domestic hot water) consumption (Portuguese regulation stuff, OpenStudio 1.6.0, E+ 8.2)

I am trying to change the peak flow rate on the shower and sink (2x) to 0.000111 x 60s x 60mn, and this would go up to 79.9 liters (In OpenStudio it is located under Loads / Water Use Consumption / Water Fixtures / peak flow rate)

Yes, I saw the video on the water heating systems, it works, but actually the value in "Peak Flow Rate" does not "stick" there, and a newly created one stays at zero.

I tried in another computer and the issue persists: is it only me or this model? I tried altering in Energyplus 8.2, which is easy, but when I import I loose the corrected values, as the systems are lost.

Can someone give it a try to check if it is a bug before reporting? Or any alternatives to make it work?

Thanks in advance.

I haven't 100% ruled out a bug, but I tested this by modifying a WaterUseDefinition and exporting the idf. What was inserted in the IDF was correct. Then I closed the model and reopened and my modified value was still there. Can you provide any additional insight into your process that might help reproduce?

Sorry for taking so long to reply, I thought I would receive an email and I was reading on all other people questions... It is right there, but maybe it is a specific file issue?

I can send you the file (don´t exactly know how). The strange thing is that I can do that change in a 32b system, but the the file gets crazy. Is there a difference also in the .osm file between 32 and 64b versions?

Hmm.. this is interesting that there may be a difference in behavior between 32 bit and 64 bit flavors. Seems unlikely but I wouldn't rule it out. You are welcome to send a file through something like drop box and I'll take a look. When you say the file get crazy, what exactly do you mean?
