WaterCAD/ WaterGEMS crashes on large scale MSX models


I've faced this problem before, but after a few updates later I faced it again. If I run a large scale (>50.000 pipes) hydraulic model with MSX(multiple species extension in WaterCAD), the results file exceeds 2GB and it crashes the whole desktop application. I guess it is because of a 32bit subprocess under the hood.

Is there a way to overcome this issue?

Thank you for your assistance in advance! (It would be critical for us to analyze results of simulations longer than just a few hours)

Best regards,
