[CIVL] Civil Engineering Instructional Software

Developed by faculty members of the Department of Civil Engineering, it is "a small collection of free instructional software from the Southern Illinois University at Edwardsville." Currently available programs include Instructional software, e.g. Stress Transformation (Two-dimensional stress transformation and Mohr's Circle), VandM (Shear and bending-moment diagrams), as well as non-instructional software such as WinTri (Trilateration Data Reduction).
