PSEUDO CODE +! +! MSHO2D is meant to divide an arbitrary polygon in triangles +! The method used is the so-called advancing boundary method +! Consider all parts that together constitute the boundary of the area +! that has to be triangulated. +! A global coarseness is computed over the whole area using a Laplacian +! method. +! If special points (array coar) are submitted the division is started by +! creating special elements around these points. +! Next the smallest part (segment) of the boundary is determined. +! First it is considered whether there can be created a triangle with one of +! the two neighbouring segments +! If so the new boundary is defined and the +! process starts again. +! If not the process goes on +! A new point is defined using the inside pointing normal. It is con- +! sidered whether this new point is really inside and far enough away +! from the other boundary lines. +! If not so it is considered whether a triangle can be formed using +! one of the already created points. +! If so the boundary is redefined and the process starts +! again. +! If not the actual considered part is placed at the back +! of the boundary array and another part is considered first. +! If so the new boundary is defined and the process starts. +! The process ends when there are no parts in the boundary, i.e. the area +! has been divided totally in triangles or when it is not possible to cre- +! ate new triangles. In that case a message is given. +! If the process has terminated normally, a repositioning is performed. +! ********************************************************************** +! +!

DESCRIPTION -! -! Fill neighbour arrays (istart and ibrpnt) for refinement -! In istart the addresses where the neighbours of point i are -! stored in array ibrpnt are stored. In this routine it is assumed -! that each point has ibrp neighbours. Neighbours of point i are -! stored from position istart(i) to istart(i+1)-1 . In the final -! form only the neighbours with nodal numbers smaller than point i -! are stored , together with the new points . If a point has more -! than ibrp neighbours, the extra neighbours are temporarily stored -! in array kelemh. Arrays istart and ibrpnt are adjusted according- -! ly in subroutine msh400. -! ********************************************************************** -! -!

PSEUDO CODE -! -! MSHO2D is meant to divide an arbitrary polygon in triangles -! The method used is the so-called advancing boundary method -! Consider all parts that together constitute the boundary of the area -! that has to be triangulated. -! A global coarseness is computed over the whole area using a Laplacian -! method. -! If special points (array coar) are submitted the division is started by -! creating special elements around these points. -! Next the smallest part (segment) of the boundary is determined. -! First it is considered whether there can be created a triangle with one of -! the two neighbouring segments -! If so the new boundary is defined and the -! process starts again. -! If not the process goes on -! A new point is defined using the inside pointing normal. It is con- -! sidered whether this new point is really inside and far enough away -! from the other boundary lines. -! If not so it is considered whether a triangle can be formed using -! one of the already created points. -! If so the boundary is redefined and the process starts -! again. -! If not the actual considered part is placed at the back -! of the boundary array and another part is considered first. -! If so the new boundary is defined and the process starts. -! The process ends when there are no parts in the boundary, i.e. the area -! has been divided totally in triangles or when it is not possible to cre- -! ate new triangles. In that case a message is given. -! If the process has terminated normally, a repositioning is performed. -! ********************************************************************** -! -!
