Error while running the simulation
I am facing an error below while running the simulation. Did I miss anything?

Time = 0.08

The error is due to not changing kinematic viscosity value. Go to transportProperties file in constant folder and change it to 1e-6. That will resolve error. Run simulation again using icoFoam command.
