## Appendix A. Overview of Parallelized Features and Known Limitations

Feature | Available in Parallel? | Limitation
--- | --- | ---
Solvers | Structured | Yes |
Unstructured | Yes |
SPH | Yes |
NBS Tet | Yes |
Rigid Bodies | Yes |
Euler Ideal Gas | Yes |
Euler Multi-Material | Yes |
Contact | Gap | Yes | Edge on edge impact is not supported.
Trajectory | Yes | Analyses using trajectory contact cannot be run in parallel if there is an SPH part or if the Decomposition Response method is selected.
Connections | Bonded/Breakable | Yes |
Spotwelds | Yes |
Reinforcement Beams | Yes |
Joins | Structured/Unstructured | Yes | Although the joins between unstructured parts have been parallelized it is strongly advised to avoid the use of unstructured parts in combination with joins in parallel analyses. An option is available that will merge joined unstructured nodes that reside at the same physical location in the model into one single unstructured node. The option is available under the Join menu and will increase robustness in many applications involving joins.
SPH-Structured | Yes |
Euler Ideal Gas | Yes |
Euler Multi-Material | Yes | Joins cannot be used in combination with Euler/Lagrange coupling.
Euler/Lagrange Interaction | Euler Ideal Gas | Yes |
Euler Multi-Material | Yes | Joined Euler cannot be used in combination with Euler/Lagrange coupling.
Boundary Conditions | Stress/Velocity/Bending Flow/Transmit | Yes |
Analytical Blast | No |
Remote Displacement | Yes |
Materials | Autodyn Materials | Yes |
Sesame Library | No |
Gauges | Fixed gauges in structured Lagrange parts | No |
Analysis Settings | Automatic Mass Scaling Update Frequency | No |
