A new Graphical User-Interface (GUI) is ready. The GUI allows you to set-up the input file for the APOLLO Blastsimulator. You can launch a simulation and monitor its progress as the GUI displays the continuously updated log-file content and diagrams of all generated history files.
The GUI writes and reads input files – that means you can also edit the input file outside the GUI (e.g. to import gauge positions from another data source) and reload it into the GUI.
The GUI is presently available for Windows only and released in a beta-mode. Please use it tentatively and give us a feed-back and report problems. Your participation in this matter is appreciated.
The specification of fluids, particles and reactions in FLUIDS and PARTICLES is now in terms of names rather than key-numbers. While hitherto the key numbers in apollo-eos.dat had to be unique, they can now be used repeatedly. Thereby the addition of variants of the same material is simplified which can all use the same key number now.
As a new feature the input file now optionally includes a section EOSFILE. Here you can specify a path/name to the eos-file that should be used for the simulation (and in the GUI) other than the default file apollo-eos.dat provided in /exe. This new feature simplifies working with modifications of EOS parameter values or addition of new material variants. A modified EOS file can e.g. be located in a project folder. If EOSFILE is used, an additional outputfile NAME_mat is produced, where the data loaded from the selected eos-file is documented; thereby the parameter values used in a run can be retrieved, even if the contents of the eos-file was modified at a later time.
A model has been implemented for the coefficient of restitution, which governs the mechanical interaction of particles with wall boundaries or embedded objects. The coefficient depends on particle velocity and temperature and is parameterized by yield strength, Youngs modulus and friction coefficient. The input of these parameter values replaces the input of a static coefficient of restitution for particle materials in Apollo-eos.dat.
The definition of particle materials and particle reactions hitherto used a hard-wired reference diameter (1 μm) for ignition criteria and burn times. The reference diameter can now be chosen arbitrarily. The Apollo-eos.dat file supplied with the new version has been modified according to these changes.
