EDGE (ExtendeD Gdml Editor) is an easy-to-use GDML editor to load and edit GDML geometries developed by Artenum.
You can find more informations on EDGE in our DOP (Detailed Offer and Pricing) or by contacting us.
The GDML format
The GDML format (Geometry Description Markup Language) is used by the GEANT4 simulation tool kit, the reference solution for particle-matter interaction. Thus, the GDML format is currently used in radiations analysis, neutronics, high-energy particles research and nuclear safety…
EDGE has been designed with the idea to facilitate the edition or creation of GDML files as there is no currently simple and accessible software. This software can create or load GDML files and save them with a real-time 3D visualization.
It allows the creation of complex GDML files by handling several-layer hierarchy and with most of the shapes handled by GDML and GEANT4, such as:
- Tessellated Elements (made of Triangular and/or Quadrangular elements)
EDGE also allows you to import pre-existing GDML defined geometries and integrate them as sub-elements of the edited geometry.
Geometry checking and validation
EDGE integrates several features to check the self-consistency of the geometry and its validity with GEANT4 based simulation kernel:
- Overlapping detection between elements to avoid errors in GEANT4 computations;
- Volume and total mass computation, taking in count the volumic mass of each elements;
- Geometry hierarchy validation and correction.
Material Properties Edition
EDGE allows to edit and attribute material properties on each geometrical elements in a simple and WYSIWYG way. Materials can be defined:
- Manually through the isotopic compositions, using a easy-to-use editor;
- From built-in GEANT4 predefined materials;
- From existing GDML defined materials
EDGE is able to import B-Rep based industrial formats, like STEP-AP203-214 and Gmsh GEO format and numerous tessellated geometries and mesh formats (Gmsh MSH, STL, UNV…).
CSG to Brep conversion
The CSG-to-Brep decomposition function allows to export GDML based geometries to equivalent ones in Gmsh GEO format, in order to open interoperability towards other simulation models, industrial CAD editors and meshers.
EDGE is powered the Keridwen Integrated Modeling Environment (IME).
