ASPHERIX®

Pre/Post-Processing

Pre- and post-processing are almost as important as the simulation itself. Aspherix® provides many tools and functionalities that ease the setup process and help to exploit the simulation results to a maximum.

Residence Time

KPIs like residence time distributions from processes which take hours used to be inaccessible to highly resolved DEM simulations – now they are accessible!

Nonspherical Shapes

Nonspherical Shapes

Aspherix® GUI provides several tools & helpers to generate nonspherical particles. One example is the superquadric builder, which visualizes the particle during its creation and adds it to the simulation automatically:

Appification

Appification

With the Appification functionality Aspherix® GUI users can create Apps out of their simulations that can be applied with almost no specific knowledge about DEM or Aspherix®. Only few parameters that should be varied are visible, all other settings are hidden (can be edited in “non-App-view” at all times but are invisible to App users).

Paraview

Paraview

Paraview macros are provided for automated postprocessing. When using the “Start Paraview” button in the GUI the data is postprocessed automatically. Alternatively, if the “aspherix_simulation.pvd” file is loaded manually, the “aspherix” macro can be applied for automated postprocessing.
