Physical space

A struct set <: AbstractPhysicalSpace defines the geometric setup of a simulation. For the structured topology, structs for 1 and 2 dimensional physical space are built.

KitBase.PSpace1D — Type
struct PSpace1D{TR<:Real, TI<:Integer, TA<:AbstractArray} <: KitBase.AbstractPhysicalSpace1D

1D physical space with structured mesh

Fields

  • x0

  • x1

  • nx

  • x

  • dx

KitBase.PSpace2D — Type
struct PSpace2D{TR<:Real, TI<:Integer, TA<:(AbstractMatrix{<:Real}), TB<:(AbstractArray{<:Real, 4}), TC, TD} <: KitBase.AbstractPhysicalSpace2D

2D physical space with structured mesh

Fields

  • x0

  • x1

  • nx

  • y0

  • y1

  • ny

  • x

  • y

  • dx

  • dy

  • vertices

  • areas

  • n

It contains:

  • x0 (y0): location of starting point
  • x1 (y1): location of ending point
  • nx (ny): number of cells in one direction
  • x (y): locations of middle points of all cells
  • dx (dy): intervals of all cell points

Besides, a unstrctured mesh struct is built, which supports 1-3 dimensional geometries.

KitBase.UnstructPSpace — Type
struct UnstructPSpace{A, B<:(AbstractMatrix{<:AbstractFloat}), C<:(AbstractMatrix{<:Integer}), D<:(AbstractVector{<:Integer}), E<:(AbstractVector{<:AbstractFloat}), F<:(AbstractArray{<:AbstractFloat, 3})} <: KitBase.AbstractPhysicalSpace

Physical space with unstructured mesh

Fields

  • cells

  • points

  • cellid

  • cellType

  • cellNeighbors

  • cellFaces

  • cellCenter

  • cellArea

  • cellNormals

  • facePoints

  • faceCells

  • faceCenter

  • faceType

source

It can be created by the built-in mesh reader.

FiniteMesh.read_mesh — Function
read_mesh(file)

Read mesh file

  • @return cells: node ids inside cells
  • @return points: are saved with 3D coordinates (z=0 for 2D case)
