What is the default lower boundary condition is for WRF?

Post by badtanjil » Fri Sep 04, 2020 1:44 am

We are running a simple vortex case for hurricane with no surface layer and with constant viscosity on horizontal and vertical direction. We are giving periodic boundary conditions on X and Y direction on namelist.input file. There does not appear to be an option to set lower boundary conditions in the namelist file and we are getting output that indicates an inviscid wall boundary condition is enabled. We want to know where in the code the lower boundary condition is set and what variables (u,v,w, theta) are set to inviscid.
