FEA was independently developed by engineers in different industries to address structural mechanics problems related to aerospace and civil engineering. The development of FEA for real-life applications started around the mid-1950s.
It is used as the basis for modern simulation software and helps engineers find weak spots, areas of tension, etc., in their designs. The results of a simulation based on the FEA method are usually depicted via a color scale that shows, for example, the pressure distribution over the object.
To be able to make simulations, a mesh consisting of up to millions of small elements that together form the shape of the structure needs to be created. Calculations are made for every single element. Combining the individual results gives us the final result of the structure.
