Hello Everyone,

I am new to CFD as well as to openFoam. I am trying a simple case of open channel flow using icoFoam solver. My geometry is a simple cuboid channel of width 0.4 m height 0.6 m and length 9m. I am neglecting the air above it and just solving it as a flow with water. The flow is steady uniform flow. Therefore the height of the water level and the velocity will be constant.
I have specified my inlet velocity and have specified pressure at outlet as atmospheric pressure and have specified the viscosity of water in transport properties file. I have used salome to generate my mesh and then exported it as unv and created the polymesh folder for openFoam. When i run the case and use paraView to visualise it, I see nothing happening. Everywhere it shows 0 velocity except at inlet where it shows the velocity specified. I will be very thankful if anyone can help.

I have changed my controldict file

startTime 0;
endTime 26;
deltaT 0.005;
writeControl timeStep;
writeInterval 80;
purgeWrite 0;
writeFormat ascii;
writePrecision 12;
writeCompression uncompressed;
timeFormat general;
timePrecision 6;
runTimeModifiable yes;

but still nothing is happening
Thanks in advance
