IntelliMesh example

IntelliMesh is a power feature that allows you to have parts of the model that are meshed very differently to be thermally attached.  In this example a detailed model of a DIP is mounted to a very simple representation of the PCB. 

Normally, to have heat transfer between different parts of the model, nodes must be shared.  IntelliMesh smartly thermally attaches parts of the model that have very different meshes. 

Not only does this allow you to create very detailed parts of your model while having others, that are less critical, to be more simple, IntelliMesh allows you to easily move one part of the model with respect to another without having to remesh the model. 

In this example we will place the component on the PCB and solve for temperatures.  We’ll then move the component to another place on the PCB and resolve to get the effect.

Shown is a side view of the board and component.  You can see that there is a gap between the DIP leads and the PCB surface.  IntelliMesh Master surfaces are defined on the surface of the PCB and Slave surfaces at the tips of the DIP leads.  When the model is solved in Solaria, the software, just by location, makes the thermal connection between the leads and the PCB surface.
Board and component temperatures.
Board temperatures.  You can see where the component lies.
After moving the component the model is resolved to get new temperatures.
