Run from any device

What you can simulate

Build models in OpenSeesPy, choose an analysis, and get displacements, forces, pressures, and drifts for research and design checks.

• Static
  Gravity, wind, and push-over

  Linear or nonlinear static analysis for frames, trusses, walls, and foundations under sustained or staged loads.

• Seismic
  Earthquake time-history

  Dynamic response under ground motions — drifts, base shear, and member forces for performance assessment.

• Geotech
  Soil, foundations, and site response

  Soil–structure interaction, liquefaction-aware materials, retaining systems, and free-field site response.

• Fluid
  Fluid–structure interaction

  Coupled fluid and structural response for dams, tanks, offshore, and other water–structure problems.

• Nonlinear
  Material and geometric nonlinearity

  Steel, concrete, soil, and contact models when elastic assumptions are not enough.

• Modal
  Eigenvalue and response spectrum

  Natural periods, mode shapes, and spectrum-based estimates before full dynamic runs.

Ways to run

Same OpenSees core — try it free, run in the cloud or CLI, then customize I/O so simulation fits the pipeline you already use.
