Pre-processor crashes when using SA-connections with user def. gate curve

[Marulke]

I am modelling a system with several storage areas (SA) and storage area connections (SAC). Its an un-steady flow analysis.

When I tried to run the model the pre-processor would start, and then nothing more happens. The pre-processor just freezes, no indication of progress, no error messages, nothing.

I have determined that this is caused by SACs of the type “weir and gate”, with user defined gate performance curves.

If I change the gate type from “user defined curve” to “sluice” or “radial”, the pre-processor will run without problems.

I guess there must be something wrong with how I have specified the gate performance curves, but I can’t find the error. Can anybody help me with this? (I have included the relevant screen shots below.)

Thanks
Marulke
