MSC Nastran is a multidisciplinary structural analysis application used by engineers to perform static, dynamic, and thermal analysis across the linear and nonlinear domains, complemented with automated structural optimization and award winning embedded fatigue analysis technologies, all enabled by high performance computing.

Engineers use MSC Nastran to ensure structural systems have the necessary strength, stiffness, and life to preclude failure (excess stresses, resonance, buckling, or detrimental deformations) that may compromise structural function and safety. MSC Nastran is also used to improve the economy and passenger comfort of structural designs.

Tekla, owned by Trimble is a software product family that consists of programs for analysis and design. Tekla software includes several applications.

Tekla Structures is 3D BIM software widely used in the building and construction industries. The software allows users to create and operate 3D structural models in concrete or steel and leads them through the process from concept to fabrication.

Tekla Structural Designer is a software app for analysis and construction design. It is used by structural engineers.

Tekla Tedds is a software solution for automating repetitive calculations. It is used in engineering for creating output such as calculations, sketches and notes.

Tekla BIMsight is an application for building information model-based construction project collaboration.
