MEDINA (short for Model EDitor Interactive for Numerical Simulation Analysis) 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. 9.0.1.2

Architecture and interfaces

MEDINA was designed as general purpose pre-/postprocessor for various areas of finite element analysis supporting most of the common CAD-formats, solvers and operating systems.

CAD-formats supported

Currently, the following CAD-formats are supported by MEDINA:

  • CATIA
  • IGES
  • JT
  • SAT (ACIS)
  • STEP
  • STL
  • VDA-FS

    • 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, particularly the following solvers are supported by MEDINA:

  • Abaqus
  • ANSYS
  • AutoSEA
  • LS-DYNA
  • Marc
  • Nastran
  • PAM-CRASH
  • PATRAN
  • Star-CD
  • SYSTUS
  • Universal
  • VECTIS
  • PERMAS

    • OS and hardware supported

    In the current release, MEDINA is running under the following operating systems and hardware architectures:

  • Linux
  • Microsoft Windows

    • FE-analysis in MEDINA

    Particularly, MEDINA is being used for the following tasks of FE-analysis:

  • Crash simulations;
  • durability analysis (thermal and mechanical loading);
  • NVH (Noise Vibration Harshness);
  • simulations about pedestrian safety and passenger protection.

    • 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 meta data 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

    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.

    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-/postprocessor for FE analysis especially in automotive industries.

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