Finite Elements programme with several modules:
The FE processor reads the general structure data and the restrictions. Basicly, the Z88 entry files can be generated by a CAD convertor Z88X, by an editor or a text processor system or with a mixed procedure. Z88X outputs the processed structure data and restrictions, calculates the stiffness matrices of the elements, compiles the stiffness matrix of the entire system, scales the equation system, solves the system with an in situ Cholesky method and displays the displacements in ASCII format.
This is why there are modules for calculating the stress, for the node strength and a net generator.
You can graphically display and plot the net generator's data.
