Sheet Lightning is a specialised engineering 2D/3D CAD System for creating and unfolding sheet metal designs for fabrication or manufacture. It handles everything from simple cylinders, cones, rectangular ducts and ovals, to adapters, adapting any of these section types, interections and multi-intersections between of any of these types to any level of complexity.

Turbine
Calculate turbine steam consumption and exhaust steam conditions. Built-in steam properties. Wide variety of units of measure included.

Universal Mechanism
The program is intended for simulation of kinematics and dynamics of planar and spatial mechanical systems. The following performances are available as results: coordinates, velocities, accelerations, reaction forces, forces in active elements etc.

Exfilt
Quickly and easily design or analyze stormwater detention ponds and below grade systems for exfiltration/infiltration. Design stormwater systems to meet exfiltration volume drawdown time criteria.

BeamBoy
BeamBoy is a free engineering utility for calculating stress and deflection of structural beams under load. May also be used for shafts. BeamBoy is menu-driven and intuitive.

OilProp
OilProp is designed to assess the core thermalphysic properties of oil and its derivatives necessary to solve transportation and processing tasks, with the minimum volume of input data.
