Hi Rob,nThanks for the output. I started from the geometry, and generated the poliedric mesh. The .prof was handled to me from another person that usednthe tetraedric mesh(generated from the same geometry). The .prof contains the (x,y,z,vx,vy,vz) for 4096 spatial points. nI guess, FLUENT should interpolate for the same geometry and a more refined mesh.n
