I'm trying to create a simulation for what is essentially a thermal switch. In order to verify the idea, I need to see where heat is flowing through the body. Is there any way to create a vector scene showing how many watts of heat are flowing through the body?

Create a Vector Field Function ("Heat Flux" here):

[-grad($Temperature)[0], -grad($Temperature)[1], -grad($Temperature)[2]]*${ThermalConductivity}

// in picture above i've forgotten a "*${ThermalConductivity}"-factor
