how to call the velocity for using in body force condition
Posted: 22 Feb 2013, 16:44
Hi everybody.... this is probably easy to do.. but i m quite new. I'm solving a heat transfer and fluid flow problem. I would like to define a body force that requires both temperature and velocity components... i can get the temperature with "variable Temperature.... but i don"t know the syntax for calling the velocity component 1 and 2...
cheers
today, 23rd february... i try to be more clear in my question...
When we want to use the variable temperature in a boundary conditions: we write in elmerGUI or .sif : Variable Temperature; MATC Real; "0.15*tx"
For the space coordinate, it is Varible Coordinate (with or without 1 2) but for the velocity?
is it : Variable Flow Solution or Variable Flow Solution[Velocity Pressure] ... can we access the variable velocity in order to reuse it as a body force, boundary conditions... if yes how do i need to declare it?
regards
