rankine vortex
 
Hi ! I am trying to simulate a rankine vortex (vortex airfoil interaction). i wrote a UDF to define the pressure, density and velocity inside and outside of the core. i ran my simulation for 1 iteration with hooking up this udf. then i unhooked the adjust function and tried to track the vortex. but the problem is when i tried to track it, it diffused so quickly. i think am setting up the boundary conditions wrong. can someone help me to setup this simulation. Thanks in advance. - Manoj
