## linkFlow - Allows user to perform civil hydraulic design tasks similar to a calculator.

The linkFlow computer program allows the user to perform civil hydraulic design tasks similar to a calculator. Vegeted and reinforced canals of any section can be designed using allowable shear and variable n values.

## IBAP - Indeterminate Beam Analysis Program

IBAP is a structural beam analysis software that can be used by Civil, Mechanical and Structural Engineers, Beam designers and Engineering students for both professional and academic purposes.

## Frame3DD - A program for the static and dynamic structural analysis.

A program for the static and dynamic structural analysis of two- and three-dimensional frames and trusses with elastic and geometric stiffness.

## XVIGAS - Beam analysis.

Xvigas analyzes the typical beams of exercises and problems. It's simple, first you define the type of beam and its characteristics, then you enter the loads and finally you get the results: reactions, internal forces and deformation.
