in this weeks spotlight we will have a look at a FEA simulation of a Gantry Crane by our PowerUser and partner @BenLewis that was used to demonstrate the process of defeaturing a geometry for a faster and easier simulation.

This project was created to demonstrate various techniques used to simplify geometry for simulation. It is also useful to demonstrate the use of elastic elements to stabilize members where “physical contacts” are used.
The webinar is mainly talking about six steps:
Preperation of the geometry
Stages of Geometry Preperation
Geometry simplifications using SolidWorks
Simulation with SimScale
Live demonstration on our platform
Demonstration of the results
The image below shows the original geometry on the left and the simplified geometry on the right. The original geometry has 2656 solid bodies. The simplified geometry has 60 solid bodies (12 structural members, 16 pins, 32 elastic stabilizing elements).
