DYNA6.1 Software

DYNA6.1 Software


The DYNA6.1 program returns the response of rigid foundations to all types of dynamic loads. The rotation of centrifugal or reciprocating machines, shock-producing machines, earthquakes, traffic and other sources of dynamic forces can produce these loads. The foundation can be supporting a single or multiple machines. The response to harmonic loading for a flexible, rectangular mat on elastic half-space or on a group of piles can also be calculated. The stiffness and damping constants of the foundation (needed for the analysis) are evaluated within the program for surface foundations, embedded foundations and piles, pile interaction in a group and other features. For rigid footings, all six degrees of freedom are considered as coupled.

The foundation stiffness and damping constants (matrices) are also returned for possible use in soil-structure interaction analysis. These constants are available for rigid footings, flexible mats (caps) on piles, or piles without any connecting cap, and also for flexible mats on elastic half-space.

  • The main engine of DYNA6.1 is double precision for more accuracy and more stability of numerical processing, especially when you have soil layers with stark difference in shear wave velocity values and/or thickness.

  • DYNA6.1 is 32 bit and 64 bit, thus is compatible with Windows 7.

  • Significantly enhanced pre- and post-processors. They make data input and getting the results much more efficient and compatible with Excel. In addition, the program now allows for automatic storage of files in subdirectories according to the name of the file run and different cases.

  • The program does not create conflicts and much easier to implement on the server with more robust control with regard to license use.

As soon as we receive your order, we will provide you with a site to download the software. Upon installing the software on your computer, the program will prompt you for an activation code. We issue the activation code based on the computer code generated by the program DYNA6.1 representing the ID of your system. You send this code to us, we e-mail you back the activation code. This whole process can take only a few minutes. There is no maintenance fee.

In order to process the order we require a purchase order and the name of the person who will sign the license agreement. Please send to the attention:
