Resistance
Introduction
Resistance boundary condition allows the user to include contact thermal or electrical resistance in the model.
Description
- This boundary condition provides an ideal option for including contact resistance or thin intervening material, such as TIMs, without creating high aspect-ratio elements.
- Resistance can be applied directly on surfaces (On surface option) or between solids (Between solid to solid interface option).
- Depending on the option used, the mouse selection control will automatically change to Face or Body pick.
- In Solid selection mode, multiple solids can be selected at once and the resistance will be applied in all interfaces between selected solids.
- The user may choose Thermal/Electrical/Both types.
- For Electrical or Both resistance types, the electrical co-simulation must be activated for this to be included in the analysis. otherwise the solver will ignore this Boundary condition
- The resistance value can be given directly or by specifying a thickness of a selected intervening material
