Kratos Multiphysics

Structures, fluids, coupled problems and particle methods.

Install

pip install KratosMultiphysics-all

Use the -all package; it resolves to the 10.3.0 set. Among the plain KratosMultiphysics 10.4 wheels one is mislabelled: the 10.4.2 build-1 wheel is tagged manylinux_2_28 but links glibc 2.34 symbols, and pip selects it for KratosMultiphysics==10.4.2 on glibc 2.28 to 2.33, where it installs without error and then fails to import. The 10.4.0, 10.4.3 and 10.4.4 wheels need only glibc 2.17, and an unpinned pip install KratosMultiphysics picks the newest release (10.4.4 in September 2026).

Then check that openPASO sees it:

python check_install.py

What openPASO knows for Kratos Multiphysics

22 kinds of problem. Ask for any of them in plain words; the names below are what the model uses internally.

Physics	Description	Dimensions	Templates
auxiliary_overview	[Reference] Kratos auxiliary applications (TrilinosApplication, MetisApplication, MappingApplication, MeshMovingApplication, HDF5Application, ...) — infrastructure that other Kratos analyses depend on. Catalog contains PyPI-publication status, deprecation notes, and FSI hidden-dependency warnings. Not a PDE physics — this is a meta-reference entry; the underlying KNOWLEDGE key is '_auxiliary_overview' (with the leading underscore preserved for backward compatibility).	2-D, 3-D	N/A
cable_net	Cable and net structures: cables, membranes, form-finding	3-D	2d
constitutive_laws	Extended constitutive laws: hyperelastic, plasticity, damage, viscoplastic	2-D, 3-D	2d
contact	Contact mechanics: frictionless Signorini (penalty active-set) — real solve via ContactStructuralMechanicsApplication	2-D	2d
cosimulation	CoSimulation framework for multi-solver coupling (CoSimulationApplication)	2-D, 3-D	2d
curved_mms	Curved-geometry manufactured solution: steady diffusion on a Gmsh-meshed annulus, real ConvectionDiffusionApplication solve (LaplacianElement2D3N), prints machine-readable L2_ERROR; theoretical P1 L2 order 2 (live-verified). Meshing is agent-driven via mesh_size or an agent-built .msh file.	2-D	annulus_2d
dam	Dam engineering: thermal-mechanical, seepage, cracking	2-D, 3-D	2d
dem	Discrete Element Method for granular/particle simulations (DEMApplication)	2-D, 3-D	2d
dem_structures_coupling	DEM-FEM coupling: impact on structures, blast	2-D, 3-D	2d
fluid_dynamics	Incompressible Navier-Stokes via FluidDynamicsApplication, monolithic VMS element (FluidDynamicsApplication)	2-D	channel_2d
fsi_partitioned	Partitioned Dirichlet-Neumann coupling driven by a KratosFSIApplication convergence accelerator (FSIApplication); a contract: each side's setup and solve are yours	2-D	2d
heat	Thermal convection-diffusion: steady and transient (ConvectionDiffusionApplication)	2-D, 3-D	2d
heat_transient	Transient heat conduction with backward Euler time integration	2-D	2d
linear_elasticity	Structural mechanics: linear/nonlinear, static/dynamic (StructuralMechanicsApplication)	2-D, 3-D	2d, 2d_nonlinear

poisson	Poisson / convection-diffusion (LaplacianElement, EulerianConvDiff)	2-D, 3-D	2d
poromechanics	Poromechanics: fracture in porous media, dam/tunnel (PoromechanicsApplication)	2-D, 3-D	2d
shallow_water	Shallow water equations: floods, dam breaks, coastal (ShallowWaterApplication)	2-D	2d
