Hi
i have geometry which has two different material . i would like to calculate the conductivity for all geometry after excitation by using comsol
how can i do that
thank you

Hello Ali,
I assume you mean the DC conductance (the inverse of the resistance) of the structure. If so, you can apply a voltage drop across the device and measure the total current flowing through, or conversely impose a total current and measure the voltage drop. Then Ohm's law is your friend.
Depending on what modules are on your license, you can use Terminal boundary conditions instead to have the software compute the resistance/conductance automatically for you.
Best,
Jeff
