| virtual void | element_reorder () |
| Reorder the elements: By default they are ordered in "horizontal" layers (increasing in x, then in y). This function changes this to an ordering in the vertical direction (y first, then x). This is more efficient if a frontal solver is used and the mesh has more elements in the x than the y direction. Can be overloaded in specific derived meshes. More... | |
| virtual double | x_spacing_function (unsigned xelement, unsigned xnode, unsigned yelement, unsigned ynode) |
| Return the value of the x-coordinate at the node given by the local node number (xnode, ynode) in the element (xelement,yelement). The description is in a "psudeo" two-dimensional coordinate system, so the range of xelement is [0,Nx-1], yelement is [0,Ny-1], and that of xnode and ynode is [0,Np-1]. The default is to return nodes that are equally spaced in the x coodinate. More... | |
| virtual double | y_spacing_function (unsigned xelement, unsigned xnode, unsigned yelement, unsigned ynode) |
| Return the value of the y-coordinate at the node given by the local node number (xnode, ynode) in the element (xelement,yelement).

| Constructor that allows the specification of minimum and maximum values of x and y coordinates and does not build the mesh This is intend to be used in derived classes that overload the spacing functions. THis is scheduled to be changed, however. The reason why this MUST be done is because the virtual spacing functions cannot be called in the base constructur, because they will not have been overloaded yet!! More... | |
