Structural / Thermal

Get Started: download and install Mecway

Examples below are all designed to be run using the demo version of Mecway (model size under 1000 nodes)

Start from the bottom, work your way up. Links to workshop files are included in YouTube video description. Models are simple, easy to change and observe effects. New examples added all the time.
