ECOMAN: an open-source package for geodynamic and seismological modeling of mechanical anisotropy

Manuele Faccenda, Brandon Paul VanderBeek, Albert de Montserrat, Jianfeng Yang, and Neil Ribe

Abstract. Mechanical anisotropy related to rock fabrics is a proxy for constraining the Earth’s deformation patterns. However, the forward and inverse modelling of mechanical anisotropy in 3D large-scale domains has been traditionally hampered by the intensive computational cost and the lack of a dedicated, open-source computational framework. Here we introduce ECOMAN, a software package for modelling strain-/stress-induced rock fabrics and testing the effects of the resulting elastic and viscous anisotropy on seismic imaging and mantle convection patterns.

Differently from existing analogous software, the modelling of strain-induced fabrics has been extended to all mantle levels and it has been optimised to run across multiple CPUs, yielding strong scaling efficiency. In addition, shape preferred orientation (SPO)-related structures can be modelled and superimposed over lattice/crystallographic preferred orientation (LPO/CPO) fabrics, which allows the consideration of the mechanical effects of fluid-filled cracks, foliated/lineated grain-scale fabrics and rock-scale layering.

One of the most important innovations is the Platform for Seismic Imaging (PSI), a set of programs for performing forward and inverse seismic modelling in isotropic/anisotropic media using real or synthetic seismic datasets. The anisotropic inversion strategy is capable of recovering parameters describing a tilted transversely isotropic (TTI) medium, which is required to reconstruct 3D structures and mantle strain patterns and to validate geodynamic models.

Short summary
The Earth's internal dynamics and structure can be well understood by combining seismological and geodynamic modeling with mineral physics, an approach that has been poorly adopted in the past. To this end we have developed ECOMAN, an open-source software package that is intended to overcome the computationally intensive nature of this multidisciplinary methodology and the lack of a dedicated and comprehensive computational framework.
