# The best 6 free programs for mechanical engineers (Part II)

Here is the second part of the best 6 free programs in mechanical engineering. You can also see the Part I of this compilation.

Dedicated to professionals with extensive experience in the sector, as well as students, this programs collection offers solutions to day-to-day work of mechanical engineers.

Banana Soft has all kinds of software organized by professional areas and professions, including mechanical.

## GeoFryPlots: Fry point-to-point strain analysis plots

GeoFryPlots performs strain analyses using the Fry point-to-point method. Data can be either read in from an ascii file (as pairs of x,y coordinates) or can be digitised directly into a data window using the mouse. Bitmap images to be digitised can be loaded into the data window from file. Fry plots are displayed in a separate FryPlot window within which a best-fit strain ellipse to the plot can be constructed using the mouse.

## Visual Probability: Calculation and drawing of probability functions

Use Visual Probability to compute and graph probability density functions, cumulative distribution functions, survival functions and hazard functions, and get quantile values, means, variances of ten more distributions.

## Open FLOWER: Resolution of Navier-Stokes equations

OpenFlower is an open source CFD software (FLOW solvER, literally) written in C++. It is mainly devoted to the resolution of the turbulent unsteady incompressible Navier-Stokes equations.
The numerical resolution relies on a finite volume approach: it can deal with arbitrary complex 3D geometries, on unstructured meshes. Possible mesh elements are numerous (tetrahedra, prisms, pyramids and hexahedra) and can all be used in a same single mesh.
The code is mainly intended to be used for Large Eddy Simulations of turbulent flows. It was first designed for Ph.D. students (and researchers) to enable exchange of knowledge about numerics and turbulence modeling, in a field (CFD) which is too often governed by commercial codes, which are unwilling to reveal what lies behind attracting flow images.

## Visual Data: Visualization of scientific data to create 3D surfaces

Visual Data is a scientific data visualization software to create 3D surface, contour plot, vector field plot, 4d scatter plots, 4d slices, 4d vector plots and isosurfaces etc.

## Strain Calculator: Strain and shear zone calculations, including general plane strain shear

Strain Calculator presents strain data and calculations graphically and numerically. Conversions of strain ratios to stretches at a given volume change can be plotted directly onto a logarithmic strain plot. Shear zone parameters (ellipticity, deformed and undeformed orientations, etc.) for any shear strain value or general shear vorticity number are calculated and shown graphically.

## Visual Matrix: a matrix calculator to implement matrix operations and matrix decompositions

The Features of Visual Matrix are:

Basic matrix operations: +, -, .*, *, ',

Determinant, inverse, rank etc.

Matrix decompositions: LU decomposition, QR decomposition.
