The M3d Nastran pre & post processor is now well established in many engineering sectors as a cheaper alternative to other commercially available packages. Although M3d is not as comprehensive as it competitor’s software many companies have realised 90% of their work doesn’t justify the cost of a full commercial license. Without the inertia which can arise in a large corporate company (where processes may not have been reviewed or adapted for many years) we are also capable of rapidly including new functionality to meet the current and immediate needs and requirements of the engineering community.
Reduce your licensing costs and increase productivity with M3d – the free Nastran Pre & Post Processor.

M3d has been written by a stress engineer for stress engineers.
