HI , m working on flow past a 2D cylinder , unsteady flow, PISO pressure velocity coupling, properties of air and velocity is 40 , i gor vortex shedding in downstream but i have two questions,
1 how to get grid lines off and got contuor filled (no meshing appear , just colours of vortex shedding)
2 someone said i have anomalies in my velocity contour


thanks in advance2.jpg

For first question, you must check "Filled" option in top left corner of the contour window and make sure nothing is selected in "Surface" panel.

For second one, you should modify your grid in order to get smooth velocity contours. Try an O-type Grid.

Bests.
