As in the title PreSRH-2D stopped due to the following "Number of nodes exceeded 500 in sec_str.f90 Weir_up Error Code is: 502"
Immediately before this message, the Command Line box said "***TVF file is read in successfully"
I do not have a weir in my model. The only thing I would suggest is unusual about this model is that it has "internal sinks" to simulate local run on in addition to the normal inlet Qs at the defined channels.
Anywhere to suggest to start trouble shooting?
