MEDINA
Encyclopedia
MEDINA is a universal pre-/postprocessor for finite element analysis.
The development of MEDINA started in the early 1990s at Daimler-Benz AG and was proceeded at debis Systemhaus. Since 2001 the support and the development of MEDINA takes place by T-Systems
International GmbH. The current release is MEDINA Rel. 8.2.
Further CAD-formats can be supported using the solution for 3D data conversion of T-Systems called COM/FOX.
MEDINA consists of two modules:
In the preprocessor all steps are taken before the computation can start, i.e.:
In the postprocessor all steps are taken after the computation of the primary data of the solver is finished, e.g.:
Important design elements to achieve high performance are parts structures and connector elements.
Within the process step of the so called “model assembly” the single FE-components (parts structures and connector elements) are merged to the complex comprehensive FE-model representing complex products like vehicles, aircraft, etc.
Single process steps or complete process chains can be automated by protocol and script techniques. Dynamic commands enable to integrate client specific plug-ins within the standard functionality of MEDINA.
.
Furthermore MEDINA is used in aerospace
, manufacturing industries, engineering service providers and universities.

- a FEM postprocessor (MEDINA.Post).
In the preprocessor all steps are taken before the computation can start, i.e.:
- Import of geometry data from CAD system;
- Import of associated meta data from the CAD-system or PDMProduct Data ManagementProduct data management is the business function often within product lifecycle management that is responsible for the creation, management and publication of product data...

In the postprocessor all steps are taken after the computation of the primary data of the solver is finished, e.g.:
- Determination of the derived secondary data;
- Illustration of the results (graphics, animations);
- Export functionalities;
- Generation of reports.
Characteristics of MEDINA
MEDINA was designed to support complex simulation tasks and huge FE models—found typically in automotive and aerospace industries—with high performance.Important design elements to achieve high performance are parts structures and connector elements.
- Parts enable an 1:1 mapping of the product structure of the CAD-/PDM-system within the FE model.
- Connector elements are used for the generic as well as solver and client specific modeling of assembling techniques like welding, bolting, bonding.
Within the process step of the so called “model assembly” the single FE-components (parts structures and connector elements) are merged to the complex comprehensive FE-model representing complex products like vehicles, aircraft, etc.
Single process steps or complete process chains can be automated by protocol and script techniques. Dynamic commands enable to integrate client specific plug-ins within the standard functionality of MEDINA.
