The software is easy to use, very intuitive interface that allows you quickly learn how it works without any training required! It's also perfect if your just starting out as an engineer or new in this field of work because its so user friendly with no complicated menus which makes everything easier when learning about sim right from scratch!! I really like their customer service team they are always there whenever i need them whether thats through live chat/email etc They respond fast even during weekends & holidays.
Nothing at all but great support services provided by such amazing people who help me solve my problem within minutes rather than hours :) Highly recommended especially since we got our first project done using sirmight simulator thanks guys :). We have been able to simulate various engineering projects including building structures (such bridges), vehicles(cars)etc easily via 3D modeling programs.
