temperature in global equation
Posted Oct 8, 2012, 3:38 PM EDT 3 Replies
I have a Joule heating model, this model includes two blocks, the upper block size is 2cm*2cm*0.5cm and the lower block size is the same.
It is assumed that the voltage difference of upper block is U1 and the voltage difference of lower block is U2.
The sum of U1 and U2 is a known value, the ratio of U1 and U2 is related to T(temperature)
I used global equation to try to find out the value of U1 and U2, the software shows the error information
'Failed to evaluate variable.
- Variable: mod1.T
- Global scope
Failed to evaluate expression.
- Expression: mod1.T'
I have given the initial value to U1, U2 and T, they are all 300.
