This example studies the natural frequencies of a pretensioned membrane exhibiting stress stiffening. The model results are compared with the analytical solution. Two different techniques for generating the prestress are explored. Mehr lesen
This is a tutorial example, showing how to work with pretensioned bolts. Various aspects of bolt modeling are explored: Modeling bolts as solids or by beams Connections of beams to solid components Bolts ended by nuts or by internal threads in the attached component Import of bolt and ...

This example models a split-and-recombine mixer channel in which a tracer fluid is introduced and mixed by multilamination. Diffusion is removed from the model using an extremely low diffusion coefficient so that any numerical diffusion can be studied in the lamination interfaces. The ... Mehr lesen
Dieses nicht-konventionelle Modell der Strömung in porösen Medien nutzt die schleichende (Stokes-) Strömung in den Zwischenräumen eines porösen Mediums. Das Modell stammt aus den von Arturo Keller, Maria Auset und Sanya Sirivithayapakorn von der University of California, Santa Barbara, ... Mehr lesen
This example shows how to perform a topology optimization with several load and constraint cases. The density feature for topology optimization is used together with a parametric sweep where each optimized solution is used as input for a further improved optimization. The final ... Mehr lesen
Micromixers can either be static or dynamic depending on the required mixing time and length scale. For static mixers, the Reynolds number has to be suitable high to induce turbulence enhanced mixing. Often micromixers operate in the laminar flow regime due to their small characteristic ...

This example demonstrates how to use the Uncertainty Quantification Module by running a series of uncertainty quantification studies for a steel bracket. This type of bracket can be used to install an actuator that is mounted on a pin placed between the two holes in the bracket arms. ... Mehr lesen
A tube connection consisting of a flange with eight prestressed bolts is subjected to a set of loads: an internal pressure, an axial force, and an external bending moment. Due to two symmetry planes, it is sufficient to only consider one quarter of the full geometry. The study ... Mehr lesen
