Can I specify different thermal conductivities for different regions in a space using Matlap PDE Toolbox? For example, the space is divided into a thermal conductivity space of 10*10*10 units, each with a different thermal conductivity.

Answer 1

There are two ways:

A good method is to generate the geometry such that it consists of a certain number of zones to which you can then assign individual conductivities.

A bad method is to write a user function in which you assign the conductivities according to the spatial position.

The last method will work if you only consider thermal conductivity dependence on temperature, e.g. But it will give bad results if the geometry is composed of different materials.
