Time dependent alternating temperature/thermal insulation boundary conditions
Hi all, I am trying to setup alternating boundary conditions for a certain boundary based on the hours of each day. My model will run for about 2 months, and I would like to set the boundary condition such that: - 0-6... Read more »
