Dynamics and waves¶
AgentFEM separates the physical study from the solution procedure. Structural dynamics can use an implicit Standard-like route or an explicit central-difference route without changing the meaning of materials, regions, loads, fields, and results.
Current routes¶
| Procedure | Character | Typical use |
|---|---|---|
| Newmark | Implicit | Structural response with controllable numerical parameters |
| Generalized-alpha | Implicit | Dynamics with high-frequency numerical dissipation |
| Central difference | Explicit | Wave propagation and short transient events |
Engineering questions to make explicit¶
- mass representation and density;
- damping model and whether it is physical or numerical;
- stable time increment for explicit analysis;
- source amplitude and time support;
- absorbing, periodic, or reflective boundary behavior;
- field sampling cadence versus integration cadence;
- kinetic, strain, external-work, and balance histories.
