A new taxonomy of issues related to CAD model quality is presented, which distinguishes
between explicit and procedural models. For each type of model, morphologic, syntactic …

Defeaturing consists in simplifying geometrical models by removing the geometrical features
that are considered not relevant for a given simulation. Feature removal and simplification of …

In adaptively weighted numerical integration, for a given set of quadrature nodes, order and
domain of integration, the quadrature weights are obtained by solving a system of suitable …

Removing geometrical details from a complex domain is a classical operation in computer
aided design for simulation and manufacturing. This procedure simplifies the meshing …

Local modifications of a computational domain are often performed in order to simplify the
meshing process and to reduce computational costs and memory requirements. However …

Significant progress has been made for assessing the influence of porosity on the
performance metrics for cast components through various modeling techniques. However, a …

Defeaturing is a popular CAD/CAE simplification technique. However, defeaturing inevitably
leads to errors that can hardly be evaluated effectively during a Finite Element (FE) analysis …

This paper provides a general framework for the quantitative estimation of the effects of
removing negative features on engineering analysis, or modification sensitivity for short …

Manufactured metallic components often contain nonuniformly distributed pores of complex
morphologies. Since such porosity defects have a significant influence on material …

The paper provides novel approaches for a posteriori estimation of goal-oriented
engineering analysis error caused by removing finite-sized negative features from a …
