Build 3D models, assign Mohr-Coulomb materials, apply gravity and loads, and solve with an explicit finite-difference engine - all in your web browser.
Structured brick grids with slope, tunnel, foundation and embankment generators.
constant-strain tetrahedra (mixed)Dynamic relaxation with local damping - the algorithm family of explicit FDM codes for quasi-static geomechanics.
Web Worker · non-blockingShear and tension failure, non-associated flow, tension cut-off.
Return mappingStrength Reduction Method computes the slope safety factor automatically.
Equivalent to "solve fos"Contour plots, slice planes, deformation scaling, stress vectors, legend.
Three.js WebGLTrack convergence ratio and displacement versus solve step.
Live feedbackChoose a geometry and set the mesh density.
Elastic and strength parameters per group, fixes and surface loads.
Run the explicit solver until convergence, or compute the FOS.
Inspect contours, slices, deformation and history plots.
The core engine is written in plain JavaScript and runs in a Web Worker, so the interface stays responsive during long solves.
