Now all my software is in zipped downloadable form. Features for each are explained. All code was written using Turbo C++ for DOS.
Matrix Inversion: Inverts up to a
15 x15 matrix using Gauss Jordan elimination method. The
rows are rearranged in each pass to use the maximum
available pivot. The determinant is also calculated. If
det=0 the calculation is terminated and a diagnostic
statement is printed. Output to screen and ASCII text
file called inv.txt
Matrix Multiplication: Multiplies
up to 15 x15 matrix. Output to screen and ASCII text
file.
Gaussian Elimination: Solves up to a
14 simultaneous equations of for Ax=b. Matrix need not be
symmetric. Output to screen and ASCII text file.
One dimensional finite element
analysis solves the truss element problem for 1 d
elasticity. It uses linear, 2 noded elements. Boundary
conditions are handled using the penalty approach. It
also handles thermal stress. Output to screen and ASCII
text file.
Two dimensional finite element
analysis solves the truss element problem for 2d
elasticity. It uses linear, 2 noded elements. Boundary
conditions are handled using the penalty approach. It
also handles thermal stress. Degree of freedom (DOF)
numbering node i has 2*i-1as the x DOF, 2*i as the y
DOF. Output to screen and ASCII text file.
Three dimensional finite element
analysis solves the truss element problem for 3d
elasticity. It uses linear, 2 noded elements. Boundary
conditions are handled using the penalty approach. It
also handles thermal stress. Degree of freedom (DOF)
numbering node i has 3*i-1as the x DOF, 3*i as the y
DOF. Output to screen and ASCII text file.
Heat transfer calculates a one
dimensional sclaer field problem. It uses linear, 2 noded
elements. Boundary conditions are handled using the
penalty approach. It handles convection, and heat input .

Beam Solves the classic (2 Dof
beam) or a three dimensional beam problem, handles
moments and forces, Output to screen and ASCII text file.
