boat motion simulation
 
Some problems
  1. my boat moves against the current without, external force. I geus it has something to do with the wrong surface roughness or shear.
  2. Which surface roughness should I fill in? What is the unit of surface roughness?
  3. Can Flow3D give an resistance/velocity curve as output?
Thanks in advance
