Quiz: Lumerical HEAT — Materials and Simulation Objects

In your HEAT simulation, you can import materials from other HEAT simulation files.

Select all the material types that are compatible with the HEAT solver. 

Which of the following can result in a more refined mesh in the simulation?

The mesh may not be adequately refined if the “max refine steps” in Auto Refinement Settings is not large enough to reach the limits defined by the mesh constraints. 

Which one of the following boundary conditions can be used to keep the bottom surface of a solid-state device’s substrate at room temperature?

Convection boundary condition is used to model the heat transfer between a solid and a fluid. 

You cannot edit your geometry objects when you are in Partitioned Volume Mode.

Which of the following simulation objects available for HEAT solver can be assigned to a reference geometry?

Assume that your 2D simulation region is formed of only 2 domains: an inner domain and an outer domain. You want a frequency-domain monitor to be assigned to all the boundaries of the simulation region (or in other words, the outer boundary of the outer domain). Which of the following reference geometries can be used to accomplish this?

You have three structures in your simulation: circle1, circl2 and circle3. The material and mesh order for each geometry object is as follows:
   Geometry                      Material                        Mesh order

Which material is used by the simulation in the region "A" where all the three geometries overlap?

To be able to form a single domain object from multiple geometric objects, they should be made of the same material. 

The use of open simulation boundaries is necessary to create an arbitrarily shaped simulation region.

Reference geometries can be used to define the geometry of structures such as rectangles and spheres.

The 2D simulation region of HEAT solver is restricted to a rectangular shape.

Imagine you need to simulate a thermally-tuned phase shifter that can be tuned with an integrated heater with a known heat generation power. Which of the following boundary conditions can model the effect of this heat on your device?

You have set up a temperature monitor in your simulation however you are not sure if the monitor is correctly aligned with your device.

Which one of the following tools will enable you to verify this?

A time-variant heat flow through a boundary can be modeled by a power boundary condition in transient mode.

You want to assign a mesh constraint object to the entire volume of a geometric object available in the Objects Tree in your HEAT simulation. Which of the following reference geometries will allow you to do this? 

You need to simulate the heating effect resulting from infrared light absorption in a metallic plasmonic nanostructure. You have obtained the amount of light absorption in the structure through an optical simulation (using DGTD or FDTD) and have imported it as the heat source for thermal simulation. Which of the following settings for the HEAT solver are suitable for this simulation?
