API

ExtendableGrids.AT_NODES — Type

abstract type AT_NODES <: AssemblyType

causes interpolation at vertices of the grid (only for H1-conforming interpolations)

source

ExtendableGrids.AssemblyType — Type

source

ExtendableGrids.GridComponentAssemblyGroups4AssemblyType — Method

GridComponentAssemblyGroups4AssemblyType(
    AT::Type{<:AssemblyType}
) -> Any

Grid component type for assembly groups of items of the given AssemblyType, e.g. CellAssemblyGroups for ON_CELLS.

source

ExtendableGrids.GridComponentGeometries4AssemblyType — Method

GridComponentGeometries4AssemblyType(
    AT::Type{<:AssemblyType}
) -> Any

Grid component type for geometry types of items of the given AssemblyType, e.g. EdgeGeometries for ON_EDGES.

source

ExtendableGrids.GridComponentNodes4AssemblyType — Method

GridComponentNodes4AssemblyType(
    AT::Type{<:AssemblyType}
) -> Any

Grid component type for node adjacency of items of the given AssemblyType, e.g. CellNodes for ON_CELLS.

source

ExtendableGrids.GridComponentRegions4AssemblyType — Method

GridComponentRegions4AssemblyType(
    AT::Type{<:AssemblyType}
) -> Any

Grid component type for region numbers of items of the given AssemblyType, e.g. CellRegions for ON_CELLS.

source

ExtendableGrids.GridComponentUniqueGeometries4AssemblyType — Method

GridComponentUniqueGeometries4AssemblyType(
    AT::Type{<:AssemblyType}
) -> Any

Grid component type for unique geometry types of items of the given AssemblyType, e.g. UniqueCellGeometries for ON_CELLS.

source

ExtendableGrids.GridComponentVolumes4AssemblyType — Method

GridComponentVolumes4AssemblyType(
    AT::Type{<:AssemblyType}
) -> Any

Grid component type for volumes of items of the given AssemblyType, e.g. FaceVolumes for ON_FACES.

source

ExtendableGrids.ItemType4AssemblyType — Method

ItemType4AssemblyType(
    _::Type{ON_CELLS}
) -> Type{ITEMTYPE_CELL}

Determine the ItemType of grid items which correspond to the given AssemblyType.

source

ExtendableGrids.L2GTransformer — Type

L2GTransformer

Transforms reference coordinates to global coordinates

source

ExtendableGrids.eval_trafo! — Method

eval_trafo!(x::AbstractArray, T::L2GTransformer, xref)

Map reference coordinates xref to global coordinates x.

Uses the mapping data of the item which was last set by update_trafo!. Result is stored in x.

source

ExtendableGrids.mapderiv! — Method

mapderiv!(M::Matrix, T::L2GTransformer, xref)

Store derivative of the inverse mapping in M.

M[j,k] holds dxref[k]/dx[j], i.e. the transposed inverse of the Jacobian of the affine map x = A*xref + b of the item which was last set by update_trafo!. Used for computation of derivatives of basis functions. For edges embedded in higher dimensions this is the tangential derivative.

source

ExtendableGrids.update_trafo! — Method

update_trafo!(T::L2GTransformer, item)

Update mapping data of T for the current item.

Must be called when entering a new item (e.g. cell). It (re)computes the affine map x = A*xref + b of that item and its determinant T.det which are used by eval_trafo! and mapderiv!. Nothing is done if the item has not changed.
