Thermal Bonded Contact

​

About this Block

What it does: This block creates a bonded contact between two FE boundaries, allowing for heat flux between the two components. Common uses:

• Domains of two regions do not necessarily share common nodes and element faces; it is necessary to “tie” these two regions together mathematically and couple them mechanically.

Tips:

• Contact resistance can be defined to account for thin membrane material at the boundary, such as thermal paste.
• The thermal contact resistance between two materials is often calculated from experimental tests of contact conductance, and the values can be found in thermal conductivity tables.
• If boundary entities can’t be found within the defined tolerance, try refining the FE Mesh or increasing the tolerance to effectively capture the connection between the two boundaries
