jayrup is on a distinguished road
Hi all
I am new to OpenFOAM i want to use simpleFoam solver an my problem is...
The problem is just like flow over a square cylinder but the inlet is having zero velocity but the square box is having some velocity say 2 m/s. Should I use moving wall concept? and What is kqRWallFunction in k file in 0 folder and epsilonWallFunction in epsilon file? i mean how do i find the values of both?
Thanks in advance
