Real3D-Analysis 

 

Real3D-Analysis is a powerful structural design / finite element analysis software designed for structural engineers of all skill levels. The software is reliable, easy to use, and affordable. It is designed for accuracy and simplicity in mind, allowing engineers to get the job done without being overwhelmed by useless features. It is available in version optimized for either 32 bit or 64 bit, and features unique 128-bit floating point (quad-precision) solver, which is able to handle numerically challenging structures. It incorporates a blazingly fast sparse solver, able to solve very large models with millions of degrees of freedom. Other key features include spreadsheet input and output, easy to use command line input, as well as compelling graphics display built upon industry standard OpenGL(R).

Since its inception in 2002, Real3D-Analysis has been licensed and sub-licensed to hundreds engineering offices in the United States and around the world. We offer various license options, including complete source code licensing. We understand you have many choices in selecting your structural software, so ask yourself this question: "Why would I pay more for something that is less accurate and more difficult to use??"

What our clients are saying:

We are a small office with a wide range of projects so our use of Real3D-Analysis is occasional. However, the graphical spreadsheet and graphical format make this an easy program to use. Over the years the improvements have added additional capability that often comes in handy. I like this program because of its ease of use, the computation speed and its ease of use whenever I need this capability. Of all of the programs like this that I have used I find that this software permits the most cost effective use of my time and the special features of this software are available for use as refinements on the initial analysis. I highly recommend its use offices of any size.

Real3D-Analysis is a lot faster than many famous structural software (like 13 seconds vs. 1+ minutes for others for the same tank structure). Using the sparse solver on another large model with 5222 nodes and six p-Delta load combinations, it only took 32 seconds. I was surprised. It's very fast.

  • 2D and 3D four-node plate/shell element, with thick or thin plate bending element (for slab modeling) and compatible/incompatible in-plane stress element (for shear wall modeling)
  • 3D eight-node solid (brick) element with compatible and incompatible formulations
  • Linear, compression-only, tension-only nodal, line and surface spring elements
  • Moment releases on frame element
  • Rigid offset and rigid links
  • Forced displacements on supports
  • Rigid diaphragms in any orientations
  • Multi-DOF constraints including inclined rollers, equal constraints etc.
  • Nodal, point forces and moments, line and surface forces, self-weight, area loads, thermal loads, pattern loads, and moving loads
 
 

Analysis and Design Options

 
  • Static linear analysis.
