Space Applications

MRADSIM is a simulation program designed to analyse satellites under space conditions to test for the effects of the radiation on the satellite that they will be affected during the total mission.

With MRADSIM, it is a software that has the ability to perform the total ionizing dose amount of any electronic and mechanical components under high radiation, linear energy transfer (LET) on the relevant geometry, dose mapping on the whole geometry and shielding studies on critical equipment optionally. With this software, it is possible to analyze the total dose of the critical electronic components in the orbital parameters that the satellite will take, according to the amount that the space radiation will take during the total duty period. In this way, your satellite design can go through the pre-design and control phase safely without the need for any experimental studies or pre-tests.

It contains STEP-> GDML conversion software designed to easily transfer satellite geometries that you have designed in 3D environment with the ability to read in GDML (Geometry Description Markup Language) format. In this way, geometry transfer is carried out smoothly.

The MRADSIM simulation program constantly updates itself using GEANT4 physical data created by CERN and uses a large material database.

How does it work?

MRADSIM is a matter-radiation interaction simulator with a user interface specially designed for space applications. The process to perform the analysis:

  • Geometry with 3D design is saved in STL format
  • For the conversion of STEP format to GDML that MRADSIM will read, geometry format conversion is performed in the program.
  • The orbit parameters of the satellite are created on SPENVIS and the radiation types and quantities are determined.
  • Physical processes and limits are determined
  • Geometric structures to be analyzed are determined and analysis type is selected.
  • The program is run on the CPU and the results are produced in many formats as graphical analyzes.
