ED-Poiss

ED-Poiss is an educational program package for the analysis of Poisson Equation using the Finite Element Method (FEM). The Finite Element Method is undoubtedly the most powerful numerical technique for solving a great variety of problems in science and industry.

Engineers using the FEM should know how to:
• calculate the element stiffness matrices,
• assemble the element stiffness matrices,
• calculate the element temperature vectors,
• assemble the the element temperature vectors,
• impose boundary conditions,
• impose external flows and radiation,
• calculate the temperature vector,
• calculate the flow field.
The goal of the educational program ED-Poiss is to introduce the user into the practical application of the FEM and at the same time reveal details of each and every solution phase.

ED-Poiss consists of 3 individual programs:

PreProcessor
 The PreProcessor is the editor of ED-Poiss and is used to enter the geometry, the boundary conditions, the external flows and the material data needed for the FEM analysis.

Processor
 The Processor is the solver of ED-Poiss and contains the actual educational FEM content. It includes an Example module, an Exercise module and a Theory module. In the Example module the user is an observer to the solution process, whereas in the Exercise module the user has to actively participate in the resolution of the structure. At any time during the calculation the user can consult the Theory module for the theoretical fundamentals of the FEM.The level of difficulty can be adjusted to fit the needs of the user.

PostProcessor
 After the structural analysis has been completed the PostProcessor is used to graphically visualize the results of the analysis, such as the temperature, the flow, etc.

The user can perform the analysis step by step. He can choose to skip individual calculation phases or he can directly go to the PostProcessor. This makes ED-Poiss an ideal tool not only for educational purposes, but also for professional users.
