Mesh for W. Wall's FSI driven cavity problem. The mesh is derived from the SimpleRectangularQuadMesh
so it's node and element numbering scheme is the same as in that mesh. Only the boundaries are numbered differently to allow the easy identification of the "collapsible" segment. Boundary coordinates are set up for all nodes located on boundary 3 (the collapsible segment). The curvilinear ("collapsible") segment is defined by a GeomObject
.

virtual void  node_update (const bool &update_all_solid_nodes=false) 
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. If a MacroElement pointer has been set for a FiniteElement, the MacroElement representation is used to update the nodal positions; if not get_x(...) uses the FE interpolation and thus leaves the nodal positions unchanged. 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. Such calls are typically made when the initial mesh is created and/or after a mesh has been refined repeatedly before the start of the computation. More...

void  convert_to_boundary_node (Node *&node_pt) 
A function that upgrades an ordinary node to a boundary node. All pointers to the node from the mesh's elements are found. and replaced by pointers to the new boundary node. If the node is present in the mesh's list of nodes, that pointer is also replaced. Finally, the pointer argument node_pt addresses the new node on return from the function. We shouldn't ever really use this, but it does make life that bit easier for the lazy mesh writer. More...  
Mesh for W. Wall's FSI driven cavity problem. The mesh is derived from the SimpleRectangularQuadMesh
so it's node and element numbering scheme is the same as in that mesh. Only the boundaries are numbered differently to allow the easy identification of the "collapsible" segment. Boundary coordinates are set up for all nodes located on boundary 3 (the collapsible segment). The curvilinear ("collapsible") segment is defined by a GeomObject
.
