| Update nodal positions in response to changes in the domain shape. Uses the FiniteElement::get_x(...) function for FiniteElements and doesn't do anything for other element types.

Virtual, so it can be overloaded by specific meshes, such as AlgebraicMeshes or SpineMeshes. Generally, this function updates the position of all nodes in response to changes in the boundary position. However, we ignore all SolidNodes since their position is computed as part of the solution – unless the bool flag is set to true.

◆ setup_boundary_coordinates() [1/4]
|
inline |
Setup boundary coordinate on boundary b which is assumed to be planar. Boundary coordinates are the x-y coordinates in the plane of that boundary, with the x-axis along the line from the (lexicographically) "lower left" to the "upper right" node. The y axis is obtained by taking the cross-product of the positive x direction with the outer unit normal computed by the face elements (or its negative if switch_normal is set to true). Doc faces in output file (if it's open).
Note 1: Setup of boundary coordinates is not done if the boundary in question turns out to be nonplanar.
Note 2: If a triangular TetMeshFacet is associated with a boundary we also store the boundary coordinates of its vertices. They are needed to interpolated intrinsic coordinates of an associated GeomObject (if any) into the interior.

◆ snap_to_quadratic_surface() [1/2]
|
inline |
Snap boundaries specified by the IDs listed in boundary_id to a quadratric surface, specified in the file quadratic_surface_file_name. This is usually used with vmtk-based meshes for which oomph-lib's xda to poly conversion code produces the files "quadratic_fsi_boundary.dat" and "quadratic_outer_solid_boundary.dat" which specify the quadratic FSI boundary (for the fluid and the solid) and the quadratic representation of the outer boundary of the solid. When used with these files, the flag switch_normal should be set to true when calling the function for the outer boundary of the solid.
