Hello,
as the listing says:
ITERATION 1 TIME: 1.0000 S
DEBIMP : PROBLEM ON BOUNDARY NUMBER 2
GIVE A VELOCITY PROFILE
IN THE BOUNDARY CONDITIONS FILE
OR CHECK THE WATER DEPTHS
PLANTE: PROGRAM STOPPED AFTER AN ERROR
You set as initial condition a constant water level elevation of 0.2m which corresponds to the bottom elevation at the inlet. So at your first time step you don't have water there and this will not work.
Mesh: in the zone near the inlet the triangle nodes don't lie on the longitudinal intersections between bottom and banks, therefore maybe you will induce some wiggles in the calculated variables, depending on the local computed water depth.
Some other remarks:
In your steering file a lot of mandatory and also other useful keywords are missing. To begin with some: time step, number of time steps, turbulence parameters, graphic and listing printout period, which variables to write into the result file, print out mass balance, continuity correction, Treatment of the linear system, etc.
Enclosed a steering file with some of the keywords listed above.
Beste regards,
Clemens
