Midas NFX: Geometry Simplification (2019 midas NFX Webinar Series)

Presentation Overview

Why to simplify?

The decision to suppress or preserve geometry strongly depends on the analysis context and the application types. 

For example, holes, fillets, and chamfers often do not significantly affect the analysis results. 

Presence of small geometrical details influence size of the FEM model. 

(number of elements is getting high)

Meshing issues - due to topological issues meshing process cannot be accomplished

Presence of wrong topology can lead to creation of highly distorted elements, which affects solution stability and accuracy.
