MEDINA (short for Model EDitor Interactive for Numerical Simulation Analysis ) is a universal pre-/postprocessor for finite element analysis . [1] [2] 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 [3]
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:
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:
OS and hardware supported
In the current release, MEDINA is running under the following operating systems and hardware architectures:
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. [4]
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 modeling of assembling techniques like welding, bolting, bonding. [5]
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.
