ANSYS: Thermal Analysis - What should be my boundary condition?
I'm trying to learn Ansys. So i have started with a simple problem in conduction which I would be using it in one of my work.
I have a wire placed between two rubber pads. I'm heating the wire electrically. The wire is routed by carving its path in the rubber pad. I need to achieve uniform temperature of 40 degree Celsius on top for that condition i need to find temperature of the wire and how long I should be heating the wire. All my setup is in room temperature . For this condition what should be my boundary condition.
I tried an automatic mesh with the following boundary conditions .
In my first attempt I gave the initial temperature as 23 degree Celsius and internal heat generation for the wire as 0.005 W/mm^3. I got the result as the elapsed time exceeds the CPU run time and also as in sufficient boundary condition.
In my second attempt i gave the temperature of wire as 60 degree Celsius and the temperature of pad to be 23 degree Celsius. Logically the temperature should flow from a higher temperature to lower temperature but in this case also I'm getting an error saying that the elapsed time exceeds the CPU run time .
Could someone help me out please . Thanks in advance.
