how to define analytic function
Posted Oct 5, 2012, 10:21 AM EDT Version 4.3 1 Reply
I am using Joule heating to simulate the voltage,current and temperature distribution.
I have 2 blocks whose size are both 2cm*2cm*1cm, I put them together to form a union(the big block size is 2cm*2cm*2cm).
I apply a voltage(U is a known value) to them in Z axis, it is supposed the voltage of upper half part is U1 and the voltage of lower half part is U2(U1+U2=U).
It is assumed the electrical conductivity of upper half part is equal to U1 and the electrical conductivity of lower half part is equal to 2*U2.
I would like to know how to set the variables and analytic function for material's electrical conductivity.
