Hi there,

i try to simulate flow around or past a circular cylinder, i define boundary conditions an select all necesarry physic models (2D, stat., steady, lam., segregated flow, stat., constant density). but always when i run the simulation, there is a thin space between the cylinder and the vectors (the spce itself is blue (no velocity) - i know i do something wrong, try it with the vector parameters...nothing happens. anybody got the same problem or a solution?? do i need a little bit of friction ??
