Grid angle in sliding meshes
for an application using sliding meshes, i need to know the grid angle at each time step. this can be done be keeping track of the timestepsize and grid speed, but i would like a more general method.
my question. how can i get this angle into my UDF, is there a variable i can query which hold the grid rotation. in the header f_slide.h, i saw a value for a rotation matrix rm but i dont know if this is it, what it is or how to use it. any help will be appreciated.
