Release of FALL3D-7.0 code
From: afolch <arnau.folch@xxxxxx>Release of FALL3D-7.0 code
************************************************************************************************
Dear colleague,
We are pleased to announce the release of the version 7.0 of the FALL3D tephra dispersal and deposition model.
We are pleased to announce the release of the version 7.0 of the FALL3D tephra dispersal and deposition model.
Relevant changes have been introduced in this new version, including:
•
A unified source code for both serial and parallel versions (only the
serial version was available for public distribution in previous
releases);
• The possibility of using forecasts/reanalysis meteorological data from several global/meso-scale meteorological models (not available for public distribution in previous releases);
• Different parameterizations available for ash aggregation. For computational reasons, a preliminary Total Grain Size Distribution (TGSD) file (furnished either by the user or generated by the pre- process SETTGSD utility program) is modified in order to create the final ”effective” granulometry file filename.grn which can include an aggregated class and a volatile species, treated as tracers;
• An option describing the cloud spreading at the Neutral Buoyancy Level (NBL) for large eruptions using a semi-analytical gravity current model;
• New parameterizations for resuspension of deposited volcanic ash by wind;

• New parameterizations for resuspension of deposited volcanic ash by wind;
• A parameterization to account for wet deposition;
• Two new parameterizations to estimate cross-wind effects on Mass Eruption Eruption (MER);
• A new multi-platform installation method that utilizes the configure command option. The program can be installed on different machines sharing the same filesystem or on a single machine that has different compilers.
