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 hours: Temperature BC
- 6-24 hours: Thermal insulation BC

The boundary condition would switch from Temperature to Insulation and vice versa each day until the end of running. I am wondering if this is possible, or if there is a more practical approach.

I would be grateful if you could help me. Thanks,
