Specifications
- Modeling for acoustic, constant-density acoustic, elastic, VTI, VTI-acoustic, TTI media
- Viscoacoustic and viscoelastic modeling
- Arbitrary (on-grid) source and receiver geometries
- Generation of shot gathers and wavefield snapshots
- Source types: explosive, shear, directional force
- Highly effective perfectly-matched layer absorbing boundaries
- Optional free-surface conditions
- Up to eighth order optimized spatial difference operators to allow for coarser grids and control numerical dispersion
- Automatic stability check gives recommendation for time step and FD operator order
- Dual parallelization for model decomposition and simultaneous multi-shot modeling
Technical specifications
- Support of 64-bit and 32-bit linux platforms
- Java User Interface with tutorial
Applications
- Micro scale: modeling of wave propagation in drill cores
- Large models: tested for model sizes larger than 1000x1000x500 cells
- 3D surveys: used for modeling a survey with >5000 shots and 3D receiver coverage, producing >1TeraByte of data
- Long-term simulations: stability has been verified for >30s of wave propagation, >20min for acoustic models
The code is available for leasing but we can realize modelling studies as well.
