Altair EDEM Professional 2020.3 | 527.7 mb
Altair, a global technology company providing solutions in product development, high-performance computing and data analytics, has released updated release of Altair EDEM 2020, the market leading Discrete Element Method (DEM) software for bulk and granular material simulation.
EDEM 2020.3 Release Notes
HyperMesh Data Export for Finite Element Analysis: Geometry contact export
HyperMesh Export dialog has been expanded to include an additional option based on the Particle-Geometry contact points. This option provides exporting of the force at the contact points rather than the existing capability which takes the forces per triangle element. This removes any mesh dependency but may result in a significantly larger data file.
Material Database reworked to allow multiple dependency groups
A new material database system has been created. This allows users to save information on a per simulation basis. Entries in the database include particle shape, material properties, interactions, Meta-Particles, contact model settings and material blocks. This functionality addresses missing components in the previous material database.
Current databases will be merged into the new database format.
EDEM API includes Geometry Deformation
Functionality has been added to the API to allow for geometries to be deformed during the simulation. This replicates the existing functionality in the Coupling Interface and makes it available for use with EDEM Contact Models. This functionality is available on the CPU initially and allows direct editing of node positions.
EEPA Model updated to include Particle-Geometry interactions
The Edinburgh Elasto-Plastic Adhesive (EEPA) contact model has been updated to include particle-geometry interactions, as well as speed improvements and minor bug fixes. The results for the particle to particle contacts remain consistent with previous versions; however, the particle-geometry interactions will be affected. These changes will give more realistic physics behavior than the previous version of the model.
Creator
Meta-Particles: add transfer material capability
Meta-particles have been added to the database transfer window and can be saved in the same way as materials, particles etc.
Support JT CAD Files
Intergraph JT CAD files (*.jt *.xml) are now supported for Geometry import.
Meta-Particles: add size distribution option
Meta-particles can now be generated with a size distribution. Meta-particles can have fixed, lognormal, normal and random distributions. Meta-particles will be scaled according to these settings when generated by the particle factories. NB. Physics model values remain unchanged during scaling.
Add Replace Geometry capability to command line
-rg -replace-geometry has been added to the Command Line. This replicates the behavior of the EDEM Creator > Replace Geometry option which replaces a geometry section but retains all attributes from the previous geometry. Options normally selected in the GUI for geometry import are replaced by a config file.
Reset the camera when Sphere Fitting Tool finishes generating particle
When generating a Particle Prototype using the Sphere Fitting Tool the camera view will update to zoom to the extents of the particle.
Support inventor CAD Files
AutoDesk Inventor CAD files (*.ipt *.iam) are now supported for Geometry import.
Analyst
Improve Contact rendering
Updates have been made to the OpenGL engine to improve contacts visualization and analyst performance (up to 70x speed improvement).
Coupling Interface
Add Replace Geometry capability to Coupling Interface
replaceGeometry() has been added to the EDEM Coupling Interface. This replicates the behavior of the EDEM Creator > Replace Geometry option which replaces a geometry section but retains all attributes from the previous geometry. Options normally selected in the GUI for ge metry import are replaced by a config file.
Add Save command to Coupling Interface
save() has been added to the EDEM Coupling Interface. This allows the simulation deck to be saved once changes have been made by the coupling interface without needing to advance the timestep.
Installer
EDEM Cal installed by default on Windows
EDEM Cal is now always installed during the installation of EDEM on Windows, allowing easier access to the software without re-running the installer.
Miscellaneous
Add micrometer option to units
Micrometers have been added as a Length unit to the interface. Micrometer based units have also been added for Acceleration, Velocity and Volume. Units can be selected through Tools > Options > Units.
EDEM 2020.3 contains fixes for the following issues:
- Performance in the Creator Particle and Meta-particle view was slow due to the number of spheres being displayed. Sphere display quality is now reduced in relation to the number of spheres used for the prototype particle. Sphere tables can now efficiently handle thousands of spheres.
- The spray factory could generate a fan shape rather than a conical shape.
- Factories using the Total Mass option were not considered complete. When restarting the simulation additional particles could be generated by the factory.
- The point of action was not copied correctly when a motion was copied to a different geometry part. Additional options have been added to resolve this issue.
- A difference in results was seen when running a simulation using the Field Data Coupling on the CPU and the GPU.
- The Sphere Fitting tool would fail to create particles from templates imported in micrometers
- An error was reported (Error -30) during the simulation when simulating using the GPU.
- A crash could occur using the Dynamic Domain with the MotionSolve MBD coupling.
- Geometries could fail during import if the filepath contained non ASCII characters.
- EDEM Cal section headings would not update when using 'next' and 'previous' buttons.
- When importing using the Rigid Body option the Min size could be greater than the Max size.
- A crash could occur when opening a deck following selecting of certain components in the options menu.
- EDEM would crash in the Analyst when clicking on a selection properties widget while the rename option was still active.
- A difference in results could be seen when using running a simulation with Linear Periodic Boundary conditions on CPU and GPU.
- Binary STL files containing 'solid' at the start reported an error and were not imported.
- Geometry import Rigid Body Mesh Min Value could not be greater than 10
- Step CAD files containing sketches could not be imported and reported and error.
- loadGeometry function could fail when running EDEM via command line.
- Classroom edition could have been preferred over professional.
- A runtime error when running EDEM-Fluent coupling on GPU.
- Certain IGES files could not be imported into EDEM.
- In GPU API, Geometry Group Index, Element ID and Index Within Type were assigned incorrectly.
- When using a stop file to stop a command line run, the generation of particles was not preserved correctly.
- File truncation and renaming errors were seen due to process conflicts at the final timestep.
- The Analysis Time reported by in the index file for the HyperMesh Export were incorrect when the simulation was run using selective save.
- HMBatch CAD import errors were not being logged in the EDEM Messages dialog.
- Particle Selection Groups were not displayed correctly when switching between multiple overlapping Selection Groups
EDEM is high-performance software for bulk and granular material simulation. Powered by state-of-the-art Discrete Element Modeling (DEM) technology, EDEM quickly and accurately simulates and analyzes the behavior of granular materials such as coal, mined ores, soils, fibers, grains, tablets, and powders.
EDEM simulation provides engineers with crucial insight into how those materials will interact with their equipment during a range of operation and process conditions.
EDEM is used for virtual testing of equipment that handles or processes bulk materials in the mining, equipment manufacturing and process industries. Companies worldwide use EDEM to optimize equipment design, increase productivity, reduce operational costs, shorten product development cycles and drive product innovation.
The 2020 release includes new coupling solutions with multi-body dynamics software Altair MotionSolve and open source, computational fluid dynamics (CFD) software OpenFOAM.
