MSC/DYTRAN is a computer-aided engineering software used in the fields of structural analysis, heat transfer, crash dynamics, electronic design automation, etc.
This manual describes MSC/DYTRAN, a three‑dimensional fluid‑structure interaction solver developed by MacNeal‑Schwendler. It covers the software’s capabilities, including explicit transient dynamics, coupling algorithms, and new material models, and explains how to set up and run analyses.
The document is organized into chapters on introduction, modeling theory, running analyses, input data, diagnostic messages, and references, plus several appendices that detail the graphical interfaces (XD YTRAN, XDEXTR), parallel processing, and integration with other codes such as ATB and USA.

The Fast General Coupling algorithm, which uses Euler mesh geometry with face normals aligned to the three basic coordinate directions, is introduced.
By defining a moving rectangular coordinate system as part of the output definition, the deformed shape can be visualized relative to that system.
The Johnson‑Cook material model was added to the shell material library.
