KratosGeoMechanicsApplication 10.4.3

KRATOS Multiphysics ("Kratos") is a framework for building parallel, multi-disciplinary simulation software, aiming at modularity, extensibility, and high performance. Kratos is written in C++, and counts with an extensive Python interface.

Geo-Mechanics Application

The Geo-Mechanics Application contains features needed for common geotechnical/geomechanical applications within Kratos Multiphysics.

Features:

• K₀ procedure, Quasi-static, dynamic

• Staged analysis

• Automatic time stepping

• 2D (plane strain and axisymmetric) and 3D UPw small displacement element for saturated and partially saturated porous media (with equal order interpolation, unstable under incompressible-undrained conditions)

• 2D (plane strain and axisymmetric) and 3D Stable UPw small displacement element for saturated and partially saturated porous media (with higher order interpolation for displacements)

• 2D (plane strain and axisymmetric) and 3D FIC-Stabilized UPw small displacement element for saturated and partially saturated porous media (with equal order interpolation for displacements)

• UPw Quasi-zero-thickness interface elements for defining cracks and joints under saturated and partially saturated conditions

• UPw Updated-Lagrangian element for saturated and partially saturated porous media (with equal order interpolation, unstable under incompressible-undrained conditions)

• Stable UPw Updated-Lagrangian element for saturated and partially saturated porous media (with higher order interpolation for displacements)

• 2D and 3D truss and cable elements

• 2D curved beam elemens with 3 nodes

• 1D, 2D and 3D steady-state and transient groundwater flow elements

• Loading User Defined Soil Models (UDSM) dll/so, written in PLAXIS forrmat

• Loading User Materials (UMAT) dll/so, written in ABAQUS forrmat

How to compile Geo-Mechanics Application

Make sure that the following lines are properly set in the configuration file:

Windows:

CALL :add_app %KRATOS_APP_DIR%\LinearSolversApplication;
CALL :add_app %KRATOS_APP_DIR%\StructuralMechanicsApplication;
CALL :add_app %KRATOS_APP_DIR%\GeoMechanicsApplication;

Linux:

add_app ${KRATOS_APP_DIR}/LinearSolversApplication;
add_app ${KRATOS_APP_DIR}/StructuralMechanicsApplication;
add_app ${KRATOS_APP_DIR}/GeoMechanicsApplication;

Note:

• MPI has not been tested and does not work.

• The UMAT/UDSM constitutive models are not included in this repository. Some practical constitutive models can be found at https://soilmodels.com for instance.
