Hello everyone, I'm a mechanical engineer and I have a problem with ansys.
I should simulate a thermoelectric generator and for now I am taking into account only one element ultimacy (attached in figure).
the 2 ends are made of copper, while the central part is made of bi2te3 (bismuth telluride). but when I try to do a thermal analysis with ansys v12 and imposed the bimuth material for the central element (despite defining a priori the seebeck coefficient, the electrical conductivity and the thermal one) gives me an error and tells me that some nn properties have been defined. . .
I should like to point out that the same analysis, made not with bismuth but with structural steel material goes well, but of course the results cannot be considered acceptable. . .
What can I do?what material could I use to replace bi2te3?some have already done such a simulation?
thanks in advance for the help!
