Hi,
I am trying to simulating sloshing problem in marine oil tankers. (2D) I have created a 2D cube which rotate about 20 degrees. center of rotation is middle of lower side. + I have used hexa mesh ( witch ICEM CFD) + laminar flow + hemougen + Free surface : 0.073 N/m Unfortunately when the cube rotates, free surface of water inside gets severe slope, which is illogical. How can I fix it? What is the problem? Please Help me. |

Please show some images of what you are getting, your mesh and CCL.
Also - do not model surface tension unless surface tension is important. It is a very expensive model to include. |
