ranas New Member qqj Join Date: Jun 2009 Posts: 12 Rep Power: 16	hi, all I use icoDyMfoam to calculate a ellipse (a/b=100) oscillating in an fluid. It works well when the non-dimensional time is less than 15. When the non-dimensional time is large than 15, the coefficiency of lift and drag become irregular, and the pressure in the flow field seems irrational. How to improve it? icoDyMfoam is compiled in double precision. best regards!!!
