Linear through finite rotation
Linear elasticity, MITC4+ shells, transient dynamics, geometric nonlinear static and dynamics, hyperelasticity, elastoplasticity, contact, RBE2, and flexible multibody workflows.
Structural analysis that remains inspectable from CAD to stress.
Prepare geometry, mesh solids, assign material and body-force data, apply surface constraints and loads, and solve with explicit numerical backends. Every setup action remains visible in the UI and editable in the generated Python journal.
Explicit numerical execution
DOLFINx and MFEM cover shared structural paths, MFEM adds Tribol contact, Kratos provides ALM contact, and the native Torso backend provides MITC4+ shells. Local PETSc and TorsoHPC solvers remain selectable.
Fields and engineering reports
Displacement, von Mises stress, principal stresses, reactions, time frames, downloadable NPZ data, and field or surface reports where available.
Model Contract
Physics stays separate from the solver backend.
Materials, BCs, and model options describe the engineering problem. Backend and linear-solver controls describe execution, allowing supported formulations to move between local, MPI-parallel, and remote solver paths without silently changing the model.
Volume conditions
Young's modulus, Poisson ratio, density, gravity acceleration, explicit body-force density, and hyperelastic parameters are assigned per solid.
CAD-bound conditions
Fixed and component constraints, prescribed displacement, traction, pressure, RBE2 attachments, and contact stay attached to persistent CAD parts and surfaces. Each mesh resolves those entities to its own boundary tags, allowing remeshing and mesh studies without reapplying conditions.
Dynamics and nonlinear controls
Newmark, HHT-alpha, and generalized-alpha time schemes coexist with Newton, globalization, damping, and model-specific controls.
Transparent solver selection
Backend, algorithm, preconditioner, device, core count, tolerances, warnings, and convergence failures remain visible and journaled.
Cases and combinations
Define named load cases, combine them with explicit factors, and run selected cases and combinations as one batch while retaining the base supports and materials.
