rotatingWallFunction not working properly
1 Attachment(s)
Hi Foamers,
I am trying simulate a rotating cylinder at transonic speeds in 2D using rhoPimpleFoam of the OpenFOAM 5.0 code package. However, the simulation output is almost the same as a static cylinder. Below is my U file with the BC that I have used.
I have also attached a contour showing the instantaneous Ma number. Top one is static and the bottom one is with the rotating cylinder.
Am I missing something here?
Code:
