I tried 0.01, it predicts high Cd value. 2. Providing Co < 1, results should not be very time dependent. A little bit difference should be acceptable....

Replies: 5 Predicted Cd is dependent on time step (pimpleFoam) Views: 252 Posted By sharonyue Predicted Cd is dependent on time step (pimpleFoam) In this test case, a Re = 1.5e4 single phase flow around a cylinder was simulated. It was found the predicted Cd is dependent on deltaT. When deltaT=1e-4, time averaged Cd equals 1.19, which match...
