Is the Distance Between Bodies Affecting Thermal Contact in Ansys WB14?

In summary, the goal is to model thermal contact between two faces, with heat flowing from the right part to the left part and a specified temperature boundary condition on the right and convection on the left. However, the contact is not working because the nodes are not meeting when traveling in the normal direction from the plane. It is suggested to check if the distance between the bodies is larger than the pinball region for the contact condition.

Trying to model a thermal contact between two faces. The plan is to get the heat flowing from the right part to the left part with a temperature BC on the right and convection on the left. At the moment the left part stays in the initial temperature so the contact obviously doesn't work.

I think the problem is because the nodes won't meet when traveling to normal direction from the plane. Any way to get the contact working?

Cheers

Actually the left part has the same temperature as the ambient temperature because of the convection.

Is the distance between the bodies bigger than the pinball region for the contact condition?
 

FAQ: Is the Distance Between Bodies Affecting Thermal Contact in Ansys WB14?

1. What is thermal contact in Ansys WB14?

Thermal contact in Ansys WB14 refers to the ability to simulate heat transfer and thermal interactions between two or more bodies in a finite element analysis (FEA) model. This feature allows for the analysis of heat flow and temperature distribution between different parts of a model, taking into account their material properties, geometry, and contact conditions.

2. How is thermal contact defined in Ansys WB14?

In Ansys WB14, thermal contact is defined as the interface between two or more bodies that allows for heat transfer. This interface can be defined through various contact types, such as bonded, frictional, or rough, which determine the nature of heat transfer between the bodies.

3. What are the benefits of using thermal contact in Ansys WB14?

Thermal contact allows for a more accurate and realistic simulation of heat transfer in FEA models. It also enables the analysis of complex thermal interactions between different components, which can help in the design and optimization of products and systems that involve heat transfer.

4. How is thermal contact set up in Ansys WB14?

Thermal contact can be set up in Ansys WB14 by defining the contact type and properties between the bodies, such as the contact stiffness and thermal conductance. The contact can also be visualized and edited using the Contact Tool in the Workbench environment.

5. Can thermal contact be simulated in both steady-state and transient analyses?

Yes, thermal contact can be simulated in both steady-state and transient analyses in Ansys WB14. In steady-state analyses, the heat transfer and temperature distribution between the bodies are assumed to be constant, while in transient analyses, the time-dependent behavior of heat transfer and temperature change can be analyzed.
