HighFrequency.assign_material

Description​

Assigns a material to selected regions of the computational domain, allowing different parts of the model to have their own electromagnetic properties.

Each region is identified by a domain ID defined in the mesh. A material can be shared by multiple regions, and different materials can be assigned to different regions of the same model.

Assigning a material to a region that already has one replaces its previous assignment.

Syntax​

obj.assign_material(material, domain)

obj

obj A HighFrequency object representing the configured electromagnetic model.

obj.assign_material(material, domain)

obj.assign_material(material, domain) Assigns the specified material to a mesh domain.

Input Arguments​

NameTypeRequiredDescription

material

Dielectric

Required

Material whose electromagnetic properties are applied to the selected regions.

domain

int | list[int]

Required

Mesh domain IDs identifying the regions to which the material is assigned.

Examples​

substrate = Dielectric(
    name="substrate",
    epsilon_r=4.2,
    loss_tangent=0.02
)
model.assign_material(substrate, domain=[2, 3])

Errors / Exceptions​

Error / Exceptions List
tanager:modelmessage:InvalidDomainType
Condition

A domain ID is not an integer.

Resolution

Specify integer mesh domain IDs.

tanager:modelmessage:DuplicateDomains
Condition

The same domain ID appears more than once in a single assignment.

Resolution

Remove duplicate domain IDs from the input list.
