Ambient thermal properties defined as variables

Hi users,

I'm studying a rather simple case (1d) where I have defined some heat and moisture transport with the use of PDEs. The reason I'm not using the predefined heat transfer modules is due to an additional source/sink term defined as an ODE.

What I need is to define the moisture content as a dirichlet boundary condition. Here, I would like to define it as a function of the ambient moisture content. So I need to extract the ambient moisture content (or relative humidity) from the weather file as a variable. Is this even possible?

Best, Mes

Hello Mes,

If you have the ambient moisture at various times in a file, this is a job for an Interpolation Function, see e.g. the Reference Manual for COMSOL Multiphysics 5.5, page 322 and following. All manuals can be accessed from within the software via File > Help > Documentation. There are also many threads that discuss Interpolation functions in this Discussion Forum.

Best regards,

Jeff
