Hi everyone,
I am trying to compute a flow above a weir but after a few iterations an problem of Integer overflow appears: "forrtl: sever <165>: Program Exception - integer overflow". In fact when I observe the results with FUDAA, a node has a water height of 10^32m.
Does someone know what does-it come from ?

Regards,
Clément

Hello,

It can be anything, it just means that the computation is unstable. Try to do smaller runs to see where the problem starts. I am just surprised that you get an integer overflow, it should be a double precision overflow...
