Free simulate software for mac

SimAssist is a Simple,Yet PowerFul 2D Ballistic Simulator.It Uses Advanced Calculation Algorithms to Simulate the Orbit of an Object In a Constant Gravity Field and its Speed at Regular Points Of the Orbit.
In a Single, Easy Oriented UI the User can Study Dozens of Simulation Graphs on the Same Sheet, and Work with them as If they Were Simple Objects.
Enhancements:
- Fixed a Minor Contextual-Menu Bug.

Requirements: Mac OS X 10.2 or later.

24U Simple Bridge is a bridge from your old plug-ins to new and better plug-ins. It is a useful tool that will help you use your old scripts with your new plug-ins without having to rewrite even a single calculation.
Upgrade your old-style 24U SimpleDialog Plug-In 2.7 or Troi Dialog 3.6 to the FileMaker Pro 7-8 native 24U SimpleDialog Plug-In 2.8 easily, without having to rewrite your calculations. Upgrade your plug-in now, and rewrite your calcs later.
Main features:
- Switch to better plug-ins without pain
- Be more flexible, more compatible
- Let users decide which plug-ins to use
- Switch now, learn later
Current bridges:
- 24U SimpleDialog Bridge - Simulate old dialog plug-ins with the new 24U SimpleDialog Plug-In
- 24U SimpleFile Bridge - Redirect Troi File functions to 24U SimpleFile Plug-In

Particula Numerica in shortly Particula is an Gravitational N-Body Simulator. The software give you REAL-TIME three dimensional images for gravitationally interacting bodies, which are thought to be stars. REAL-TIME isnt meant real stellar time but you can see the MOTION of stars. The time indicated in the software is normalized time.

Particula can simulate the gravitational interaction of many bodies with certain initial conditions. You may set a simple homo-temperature spherical distribution model as an initial condition. The temperature and the number of the particles are able to be set. You can also use NEMO ASCII files as an initial data.

Particula provide you both two and three dimensional view. It shows you the overall 3D view of the particles. In 2D view you can see a trajectory of a certain particle and the temporal variation of potential energies (Kinetic/red and Potential/blue).

To update the 2D view you should click mouse with Ctrl key or the right mouse button. To change the line of sight in 3D view, just drag to rotate and shift-drag to zoom in/out.

Enhancements:

• Friendlier to Mac users.
• Many new commands were added to enhance the MW scripts for both 2D and 3D simulations.
• The latest version of Jmol can now be used as a plugin.
• Force vibrations can now be added to make models that simulate artificial life as those in the Sodo Constructor.
• Many new models were added.
• Many other improvements and bug fixes.

Requirements:

• Mac OS X 10.4 or later
• Java 1.5 or later.

safecopy is an open source data recovery tool which tries to extract as much data as possible from a problematic (i.e. damaged sectors) source - like floppy drives, CDs, tape devices, harddisk partitions, ..., where other tools like dd would fail doe to I/O errors.
A main problem with damaged storage hardware is, that once you get an unrecoverable IO error further reading from the file / device often fails until the file has been closed and re-opened.
The normal copy tools like cat, cp or dd do not allow creation of an image file from a disk or CD-ROM once reading of a sector failed.
Safecopy tries to get as much data from the source as possible, even resorting to device specific low level operations if applicable.

Enhancements
- Safecopy has been internally redesigned to improve reliability and predictability of behavior.
- It now comes with a textual behavior specification and a self test suite, complete... with a glibc wrapper library to simulate IO errors on virtual files.
- Blocksize autodetection now also works in combination with low level device access. Blocksizes can now be specified as a percentage of the file size or as multiples of the hardware blocksize, making these options much easier to use.
- New option presets provide shortcuts for multi-stage data rescue with minimum commandline typing effort
