MEDINA, short for Model Editor Interactive for Numerical Simulation Analysis, is a universal pre-post processor for finite element analysis. The development of MEDINA began in the early 1990s at Daimler-Benz AG based on previous work done at debis Systemhaus. In 2001 the support and development of MEDINA was taken over by T-Systems International GmbH. The current release is MEDINA Rel. 9.0.1.2.

Architecture and interfaces

MEDINA was designed as a general purpose pre-post processor for various areas of finite element analysis (FEA) supporting most of the common CAD formats, solvers, and operating systems.

CAD formats supported

Currently, the following CAD formats are supported by MEDINA:

Further, CAD formats can be supported using the solution for 3D data conversion of T-Systems called COM/FOX.

FEA interfaces supported

In the current release, the following solvers are supported by MEDINA:

OS and hardware supported

In the latest release, MEDINA is running with Linux and Microsoft Windows.

FE-analysis in MEDINA

Particularly, MEDINA is being used for the following tasks of FEA:

MEDINA consists of two modules:

  • a FEM preprocessor (MEDINA.Pre) and
  • 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 metadata from the CAD-system or PDM-system.
  • Import of FE-models.
  • Editing and repair of CAD geometry.
  • Meshing.
  • Model structuring.
  • Definition of material parameters.
  • Definition of boundary conditions.
  • Definition of load cases.
  • Generation of the solver specific input deck.

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 media

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 a 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 modelling of assembling techniques like welding, bolting, and bonding.

Within the "model assembly process step," the single FE components (parts structures and connector elements) are merged into the FE model, representing products like vehicles, aircraft, etc.

Protocol and script techniques can automate single process steps or complete process chains. Dynamic commands enable the integration of client-specific plugins within MEDINA's standard functionality.

Target groups/user groups

Due to the development roots of MEDINA and the included functionalities for the analysis of huge FE-models, MEDINA is a widely used pre-/post-processor for FE analysis especially in automotive industries.

Furthermore, MEDINA is used in aerospace, manufacturing industries, engineering service providers and universities.
