Acoustic
6 classesConstant-density acoustic wave equation. Most-used family; default for FWI.
AcousticDefault. Second-order in time, PML boundaries.
Acoustic1stFirst-order velocity-stress formulation.
Acoustic3D3-D extension. Larger memory footprint.
AcousticVRZVariable density via vertical impedance perturbation.
AcousticLSRTMLSRTM-aware acoustic; mp reflectivity perturbation field.
AcousticLSRTM3D3-D extension of LSRTM-aware acoustic.
Elastic
2 classesParticle velocities and stresses. Required for converted-wave physics.
Anisotropic
2 classesTTI elastic media with rotated symmetry axis. Required when tilted shales / layering matter.
DAS family
8 classesDistributed-acoustic-sensing strain / strain-rate operators on top of the elastic wavefield. Zhao, Mu, Elastic, and Modeler formulations; 2D + 3D.
Propagators
2 classesWrap any equation into a callable solver. Equation-agnostic; same API for every physics family above.
