Model Editor Interactive for Numerical Simulation Analysis (MEDINA) is a universal pre-post processor for finite element analysis. MEDINA is a tool designed to support complex networking and simulations in the product development process and has been used in the automotive and aerospace industries. The development of MEDINA began in the early 1990s at Daimler-Benz AG building on previous work carried out at Debis Systemhaus. In 2001, T-Systems International GmbH took over the support and development of MEDINA. The current release is MEDINA Rel. 9.0.1.2.

Architecture and interfaces

MEDINA has been developed as a versatile pre- and post-processing tool for various domains within finite element analysis (FEA). It is compatible with most widely used CAD formats, solver applications, and operating systems.

CAD formats supported

Currently, the following CAD formats are supported by MEDINA:

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

Furthermore, additional CAD formats can be supported using T-Systems’ 3-D data conversion solution, COM/FOX

FEA interfaces supported

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

FE-analysis in MEDINA

Currently, MEDINA can be used for the following FEA tasks:

• 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 pre-processor (MEDINA.Pre)
• A FEM post-processor (MEDINA.Post)

In the pre-processor, 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 post-processor 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 with high performance in mind. It implements 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 modeling of assembling techniques like welding, bolting, and bonding

Within the "model assembly process step", the individual FE components (part 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 its development roots and built-in functionalities for analyzing large FE models, MEDINA is used primarily as a pre- and post-processor for FE analysis in the automotive industry, as well as in aerospace, manufacturing, engineering service providers and universities.
