Hallo
I'm using ANSYS 15.0.7 Workbench and I try to solving a problem which includes thermal and electric phenomenas. When I try to solving the same problem by just using
either thermal or electric analysis it will be solved. But not when I using both at the same time. I know that the equations are much more difficult by solving
a thermal-electric problem. Ansys 15 workbench has this opportunity. But I couldn't find any example of such a solution.
Here are one example of properties which I tried. But it seems to me that doesn't metter what I use, thermal-electric problems leads to a error in ansys.
Analysis Systems: Thermal-Electric
Geometry: A wire (resp. cylinder) with a length of 1000mm and diameter 0.006m
Mesh: default
Steady-State Thermal-Electric Conduction:
Current: 10amps on one surface of the wire
Temperature: 20°C on one surface of the wire
Solution:
Error: The solver engine was unable to converge on a solution for the nonlinear problem as constrained. Please see the Troubleshooting section of the Help System for more information.
Warning: The unconverged solution (identified as Substep 999999) is output for analysis debug purposes. Results at this time should not be used for any other purpose.
I would be very thankful if someone has an idea what the error could be or if someone solved a similar proplem and could tell me how he solved the problem.
I just made my example as simple as possible in order to show you my error. The target is to analyse the temperture distribution inside of cables at certain current supply.
