Seismic simulation now added to workflow in cdem2Ddesktop
Seismic Simulation
From realistic, mechanically-modelled, geological structures to depth-migrated seismic sections

From realistic, mechanically-modelled, geological structures to depth-migrated seismic sections
I have developed an integrated, multi-stage numerical pipeline that bridges discrete element modelling (DEM) and reflection seismology by converting particle-based structural simulations into depth-migrated seismic sections.
A structural to seismic bridge
From realistic, mechanically-modelled, geological structures to depth-migrated seismic sections
From realistic, mechanically-modelled, geological structures to depth-migrated seismic sections
The workflow firstly maps particle-based discrete element outputs (coordinates, radii, density, velocity) onto regular spatial grids using bounding-box spatial interpolation.
Forward seismic modelling engine
From realistic, mechanically-modelled, geological structures to depth-migrated seismic sections
It then computes acoustic impedance and generates synthetic seismic sections via phase-shift upward wavefield extrapolation and Ricker wavelet convolution.
Advanced depth imaging
The final stage is Phase Shift Plus Interpolation (PSPI) post-stack depth migration with local velocity interpolation and absorbing boundary conditions to resolve complex structural geometries.

In addition to viewing within the Application we also output fully calibrated velocity models and seismic sections in text, raw binary, and SEG-Y formats.
