Input Editor Pane Mesh

In this pane, all parameters related to the mesh are displayed.

Neither the dimensionality of a model nor the number of nodes and elements can be changed once the mesh was created.

Nodal coordinates

The nodal coordinates can be changed in a separate dialog that is invoked by the button "Nodal coordinates and boundary conditions". Note: HbgcJava does not check the validity of the resulting mesh.

The "Node finder" dialog can be used to find the closest node of the mesh to a given set of coordinates. This dialog is available from the Tools menu of the main menu bar.

Note: A more detailed description of boundary conditions is here.

Nodal boundary conditions

Nodes can have these types of boundary conditions: Point source (also called well nodes), Dirichlet (fixed concentration), and no boundary condition. All of these can be applied to any node of a mesh, not just the outer boundary.

Element incidences

Element incidences can be edited, but this feature should be used with great caution. There is currently no check for the validity of the resulting mesh.

Elemental boundary conditions

All elements can have either distributed source boundary conditions or no boundary condition. Boundary element sides can also have variable boundary conditions.
Note: It is currently not possible to modify elemental boundary conditions for 2D and 3D simulations.
