OpenSees (Open System for Earthquake Engineering Simulation) is a software package for simulating the seismic response of structural and geotechnical systems. With version 2.5.0+ CCR supports serial (OpenSees) and parallel (OpenSeesSP and OpenSeesMP) implementations.
Availability: Open access for all academic users

About the OpenSees Binaries
- OpenSees: The OpenSees binary is for running OpenSees on a single processor. It is a good choice for solving small models that don't require a long time to solve.
- OpenSeesSP: The OpenSeesSP binary is for solving a model in parallel using MPI-enabled solvers (e.g. SuperLU and MUMPS). It is a good choice for large models that would take a very long time to solve using the OpenSees binary.
- OpenSeesMP: The OpenSeesMP binary is for distributing many models runs or other independent OpenSees processing tasks using MPI as a task launcher. It is good for parallelizing parameter sweeps, sensitivity and uncertainty analyses, and simulation-based design optimizations.
Examples have been created for using the opensees module in different contexts and these may be found in the CCR's "$UTIL/academic" storage area.
