Geometry Setup Tips in Ansys Lumerical HEAT — Lesson 7
Partitioned Volume Mode
The Ansys Lumerical HEAT solver divides the simulation region into partitioned domains and surfaces before running the simulation. In this video lesson, you will learn how the domains are formed and how to visualize them.
Reference Geometries
Reference geometries can be used to assign various simulation objects such as boundary conditions, sources and monitors to any desired volume or surface in the simulation. This gives you the freedom to apply attributes to arbitrary geometries. This video lesson will walk you through the concept of reference geometries, their types and applications.
Mesh Order
The mesh order property governs how overlapping objects are meshed in the simulation. In this video lesson, you will learn about the rules applicable to the mesh order so that you can correctly represent the index profile of your structures in the simulation.
Preserve Surfaces
Preserving surfaces can be used to form domains regardless of mesh order when there is overlap between objects. In this video, we will demonstrate the concept using two overlapping objects.
Merging
Sometimes you need to form a complex geometry by merging multiple geometries. In this video, we will demonstrate how geometries can be merged by disabling the “preserve surface” option.
Open Simulation Boundaries
By default, the extent of the simulation is determined by the simulation boundaries. In this video, you will learn how to define the simulation region based on geometry.
