FEA Software¶

Here is a collection of useful links and information regarding the currently supported FEA solvers

Code Aster¶

Code Aster is distributed as a conda-forge package and can be used together with adapy. It is available for Linux and, since version 18.1.7, for Windows (sequential MSVC builds). Add it to the same pixi project as adapy, so the analyses adapy starts find the solver in that environment:

pixi add ada-py "code-aster>=18.1.7"

To have Code Aster on its own, outside any project:

pixi global install "code-aster>=18.1.7"

More information about Code Aster can be found on

Calculix¶

Calculix is distributed on conda-forge package and is now a dependency of adapy. It is supported on all platforms.

OpenCourant¶

OpenCourant is the community fork of OpenRadioss: an open-source explicit dynamics solver for impacts, drops and other short, nonlinear events. adapy writes its starter and engine decks, runs both stages and reads the animation results back:

from ada.fem.steps import StepExplicit

a.fem.add_step(StepExplicit("impact", total_time=0.06))  # with output_interval / target_dt as needed
res = a.to_fem("impact", "opencourant", execute=True)
res.show()  # a time history: the step slider becomes a timeline

• Decks: <name>_0000.rad (starter) and <name>_0001.rad (engine). Supported so far: 3- and 4-node shells, elastic and Johnson-Cook metals, fixed boundary conditions, initial velocities, and symmetric shell-to-shell contact. Anything else raises NotImplementedError rather than being dropped silently. Beams and plates can be meshed as shells only with ada.fem.meshing.mesh_shell_bodies().
• Results: the run's animation states are packed into one .radanim file, which reads as an FEAResult and uploads to Ada Studio like any other result. There it plays as a time history and can be exported as MP4 or GIF.
• Solver: adapy runs the executables of the opencourant conda package (linux-64), which must be on PATH. The package is not on conda-forge yet.

examples/opencourant_cell_impact.py is a complete run: a shell box dropped onto one steel cell, with contact.
