Calculating variables relating to wall function in Transient simulation
 

Hey Everyone,

I am trying to figure out how to calculate the shear stress, and yplus for my simulation in CFX-post. I am running a transient simulation, (using adaptive time stepping) since I couldn't achieve convergence using steady state simulations. I am using the SST turbulence model.

When I ran in steady state, I could just go to the variable selector and click the variables I needed to calculate. However, now that I am running a transient simulation, non of the variables I need to calculate are there. Shear Stress, yplus. Am I going to have to input all these as variables and define them myself?

Thanks for all your help!
