ECOMAN: Exploring the COnsequences of Mechanical ANisotropy
ECOMAN is software package for computing elastic and viscous mechanical properties of crustal and mantle rocks.
ECOMAN2.0 includes software for:
A) simulation of the strain-induced evolution of mantle rock intrinsic/extrinsic fabrics (ECOMAN2.0-geodynamics):
D-REX_S: Single Aggregate Fabric. This software builds on the original D-REX and estimates the strain-induced LPO of a single mantle aggregate. It includes the necessary MTEX software libraries to generate pole figures of the (1) LPO and (2) isotropic/anisotropic elastic properties.
D-REX_M: Multiple Aggregates Fabric. This software builds on the original D-REX and computes the strain-induced LPO of multiple mantle aggregates and output their (1) deformation gradient tensor F and (2) elastic tensor C as a function of the crystals orientation, volume fraction and of the local P-T conditions.
EXEV: this software computes the EXtrinsic Elastic and Viscous anisotropy using Effective Medium Theories (STILWE and DEM). It includes also (1) a parametrization of the viscous tensor evolution as a function of the deformation for 2 phases (matrix-inclusion) systems to be used in large-scale mantle convection simulations, and (2) the software VIZVISC to visualize the amount of strain-induced, extrinsic viscous anisotropy.
B) visualization of the mechanical properties (ECOMAN2.0-geodynamics):
VIZTOMO: this software processes the D-REX_M output for (1) visualization of the aggregates elastic and deformational history (FSE) properties, and (2) preparing the initial setup for seismic wave propagation simulations (e.g., SPECFEM3D).
VIZVISC: this software processes the D-REX_M output for visualization of the aggregates viscous and deformational history (FSE) properties.
C) Seismic forward and inverse modelling (ECOMAN2.0-seismology):
SKS-SPLIT: this software estimate the SKS splitting at a grid of virtual seismic stations placed at the top of the D-REX_M model as a function of the back-azimuth using the FSTRACK software (Becker et al., 2006).
PSI (Platform for Seismic Imaging): is a Julia package for performing tomographic inversion of both real and synthetic seismic datasets. PSI can be used to forward model P and S travel-times, splitting intensity (Chevrot, 2000), and shear wave splitting parameters (i.e. the fast-polarisation azimuth and the delay time between the fast- and slow-polarised waveforms).
