Sections

Within Cthonios, sections refer to groups or "blocks" of elements that share a common element topology and material model. We allow by default for each element to possess different fixed material properties and an arbitrary number of state variables. Since the material model is the same for all elements in a section, the number of state variables will be the same at each element/quadrature point.

Cthonios.AbstractSectionInternal — Type
abstract type AbstractSectionInternal{P, F} <: Cthonios.AbstractSection

Abstract type for section internals. P corresponds to the physics F corresponds to the formulation

source
Cthonios.Section — Type
struct Section{P} <: Cthonios.AbstractSectionInput

  • physics::Any

  • block_name::String

  • q_order::Int64

Section inputs. physics - Physics object to use in this section. block_name - Name of exodus block to construct section from. q_order - Quadrature Order to use

source
Cthonios.SectionInternal — Type
struct SectionInternal{P, F} <: Cthonios.AbstractSectionInternal{P, F}

  • physics::Any

  • block_name::String

  • fspace::Any

Section internals. physics - Physics object to use in this section. block_name - Name of exodus block to construct section from. fspace - Function space for this element type

source
Cthonios.SectionInternal — Method
SectionInternal(
    mesh,
    dof,
    section
) -> Cthonios.SectionInternal

Constructor for SectionInternal. mesh - FileMesh object. dof - DofManager object. section - SectionInput object.

source
