Dear Colleagues, Greeting, I'm Samar Akef, I need your help for adding a lockup table in thermoelectric model, how can i get the relation between the temperature and each of the following: 1-Seebeck coefficient. 2-Thermal Conductivity. 3-Electrical Conductivity.

Hello Samar,

Look-up tables can be introduced with interpolation functions, see here

Best,

Jeff

Best,

Jeff Dear Jeff, Thanks for your fast reply, Can you clarify to me in the Thermoelectric model the relation between the temperature and each of the following: Seebeck coefficient, Thermal and Electircal Conductivities which are using in the lock-up table?

Hello Samar,

I am not sure I understand your question correctly. Material properties such as the Seebeck coefficient and the thermal and electrical conductivities are inputs to the model that the end user of the software either selects from those provided in the software or supplies in the form of contants or functions (and you earlier expressed an interest in supplying them as functions of temperature via a look-up table). With those material properties selected/specified by the end user, the software solves the classical equations for electricity and heat transfer. See for instance this webinar which presents thermoelectric device modeling with COMSOL's Heat Transfer Module.

Best,

Jeff
