This web page documents three pieces of software dealing with the comprehensive modeling of flexible multibody systems.
Dymore is a finite element based multibody dynamics code for the comprehensive modeling of flexible multibody systems. Dymore has been implemented in industrial settings, it is presently used by a number of rotorcraft, wind energy, and aerospace companies and research laboratories.
SectionBuilder is a finite element based tool for the analysis of cross-sections of beams of arbitrary configuration made of anisotropic materials. SectionBuilder is seamlessly integrated with Dymore to automate the analysis of geometrically exact beams within the framework of flexible multibody systems.
NormalBuilder is a finite element based tool for the through-the-thickness analysis of laminated composite plates and shells. NormalBuilder is seamlessly integrated with Dymore to automate the analysis of geometrically exact plates and shells within the framework of flexible multibody systems.
The following information concerning these codes is available.
The input files needed to run these three, fully integrated codes are described in details in the user's manual.
Sample applications and movies can be downloaded.
A number of benchmark test cases are proposed for the validation of flexible multibody dynamics simulations. Each benchmark test case is described in details and predictions for various codes are available for comparison.
An installation notice is also available. Dymore uses freely available, cross-platform, compilers, graphical user interface, and graphical packages only.
