Spatially varying BC
I am trying to set up a floor boundary condition that turns on boundary layer growth in order to model a windtunnel floor with a known suction point. I heard this can be done with field functions. How do I:
I have made some progress with my problem in that I know how to reference positions in x,y,z now which I previously didn't. I have also seen how "method" can be changed from constant to "field function" for various types of BC.
What I am now stuck on is how to use these methods to turn slip on or off. I dont think it can be done, should I look for an alternative method, such as creating multiple walls?
Think I've been led down the wrong route by my adviser...
