Conversion from SOLIDWORKS to Nastran is not supported yet :(

SOLIDWORKS is a modeling CAD and CAE program by Dassault Systemes which runs on Windows. It is built on Parasolid kernel. SOLIDWORKS user base covers a very wide range of manufacturing market segments, such as aerospace, transportation, electronics, machinery, medical, etc.

SOLIDWORKS users are capable of drawing 2D and 3D sketches, creating models and assemblies, adding notes, dimensions and tolerances.

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.
