How to Use This Manual

This manual provides specific information about the commands and features of Trelis. It is divided into chapters, which roughly follow the process in which a finite element model is created, from geometry creation to mesh generation to boundary condition application. Examples are provided in the tutorial chapter. Appendices contain advanced topics, alpha commands, summary of APREPRO functions, FASTQ reference, a troubleshooting guide, and references.


Integrated in Trelis are algorithms and tools, which are in a user-beware state. As they are further tested (often with the assistance of users) and improved, the tool becomes more stable and production-worthy. Since documentation of the tool is necessary for actual use, we have included the documentation of all available tools. However, a "hammer" icon is placed next to some capabilities as a warning.
