The main purpose of FEM19 is to provide a simple way to define the geometry of a considered plane object. A user adds curves and points which define a plane object in any order and orientation. The program then builds solid model and generates a triangular mesh. Setting the material properties, boundary conditions, and solution procedures are implemented more or less in an ordinary way.
Graphical outputs and geometric computation are based on libraries:
-draw2d (https://www.mathworks.com/matlabcentral/fileexchange/71745-draw19),
-drawAPT (https://www.mathworks.com/matlabcentral/fileexchange/71751-drawapt) and
-gearInMesh (https://www.mathworks.com/matlabcentral/fileexchange/71968-gearsinmesh),
which are for convenience also included into FEM19.
The mesh generators are ADF2D [1] and MESH2D ([2]). ADF2D is part of the library, MESH2D must be downloaded separately. The numerical solver is based on the MINIFEM program [3]. Profile reduction is done by the Sloan algorithm [4].
The program is meant to be used as an educational and research tool.
