ED-Tridim ED-Tridim is an educational program for the analysis of 1D, 2D and 3D framework and pin-joint structures using matrix methods.Todays structural analysis methods are all based on matrix techniques. Matrix analysis is vital for applying the theoretical fundamentals and the numerical procedures in a clear and compact manner.

ED-Tridim consists of 4 modules:

The Theory module summarises the fundamentals of structural analysis using matrix methods.It includes a theoretical appendix (with the user manual) and a Windows-based Help system (with the programs) that can be accessed at any time during the solution process.

The Library module is the editor of ED-Tridim and can be used to generate and/or modify any kind of 1D, 2D and 3D framework or pin-joint structure. This includes material data, different load types and boundary conditions. There is no size limit for generating new structures.

In the Example module the structural analysis process is entirely carried out by ED-Tridim. The user merely follows the step by step instructions of the program, i.e. the node numbering, the assembly of the stiffness matrix and the load vector, applying boundary conditions etc.

In the Exercise module the user is asked to interactively participate in the structural analysis process. Here ED-Tridim merely act as a guiding or counseling tutor. In cases of doubt the program can perform steps which are unclear to the user.

The user can perform the analysis step by step. Alternatively he can skip individual calculation phases or he can directly go to the final solution. This makes ED-Tridim an ideal tool for both educational purposes as well as for professional users.
