Conversion from Simlab Composer to Nastran is not supported yet :(

Simlab Composer is a visualization and VR creation software by SimLab Soft. It is applied in creating renders, building VR scenes, and running simulations.

Simlab Composer provides users with a possibility to import, visualize, render, and animate 3D CAD models, share and collaborate, automate and improve visualization and simulation workflows.

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.
