Default patch radial velocity
Posts: n/a

Im doing a simple transisent simulation in 2D.

To describe the innitial state I initialise the domain, create a small region (circle) in the sentre of the domain and then patch innitial values (like temperature) to it. The question is how can I patch a radial velocity to this small region in the middle of the domain. By radial I mean "outwards spreading in all directions". If I use axisimetric mode in solver and patch "radial" velocity I get velocity only in one direction...
