Fluid Structure Interaction – Impeller
This a a short case study of one way fluid structure interaction on a centrifugal compressor. The stress fields on the impeller of a centrifugal compressor are due to centrifugal forces, aerodynamic forces… Continue reading
Break out Modeling
Intro A break out model is a simulation model which represents a small portion of the initial model. For very large models this technique is useful to capture a more accurate representation of… Continue reading
Non-linear quasi-static analysis with contact
A gasket (blue) is between two cylindrical tubes and the outer cylinder is subjected to a pressure. Modeling aspects of this case include: Non linear implicit static analysis Contact modeling Elastoplastic material… Continue reading
