Abstract : This Memorandum describes two computer programs which have been developed as data preparation tools for the three dimensional boundary integral equation (BIE3D) computer program. The first is a threedimensional mesh generation computer program which is based on a semi automatic subdivision technique similar to a twodimensional finite element mesh generation procedure. The program is written in standard FORTRAN and it is now operational in the Materials and Structures Departmental VAX computer. The second is a computer program for plotting the generated mesh. The plotting program is used to draw a three dimensional view of the mesh of a problem. In particular, a generated mesh can be drawn so that its topology can be checked visually for anomalous points and incompatibility of elements. The program is written in BASIC and it runs interactively on a HewlettPackard HP2647F graphics terminal. Both computer programs are described with examples. Instructions and descriptions for both input and output data file are presented in each case. Keywords: Three dimensional; Mesh generation; Boundary element method; 3D computer graphics.
