Hi everyone,

i'am trying to find a way to model a heat transfert (Conductivity) between two cube of different materials.

the block (thermal conductance) of simscape is designed to be used to represent conductivity for the same material.

You just need to put 2 conductivities in series, one for each material.

For modelling heat transfer between two cubes as rightly suggested by Carlos, you can use two “Conductive Heat Transfer” blocks in series.

Add the “Thermal Mass” blocks, connect the ends to the “Conductive Heat Transfer” blocks in series. Just make sure to edit the correct “Specific heat” in “Thermal Mass” block and “Thermal conductivity” in the “Conductive Heat Transfer” block for the respective cube.

Here is an image, modelling heat transfer between aluminium and iron cubes that you can refer:
