This example illustrates the modeling of a tensegrity table. The table is made of two rigid bodies connected through a central wire and four outer wires. Two cases are analyzed. In the first case, the top of the table is loaded with vertically downward acting load of varying magnitude. ... Mehr lesen
This model demonstrates 2D topology optimization for the problem of minimum mass subject to a compliance constraint and a stress constraint. The stress constraint is implemented with a P-norm global aggregation function. The stress input to this is interpolated differently than the Young ... Mehr lesen
This example shows how to model Lithium diffusion in a silicon electrode that swells. The model shows how swelling-induced plastic deformation can increase the maximum state of charge (SOC). Mehr lesen
Gradient-based optimization is an efficient way of computing better values for many control variables. This example optimizes diameters of individual members in a truss structure such that the structure becomes stiffer without adding mass to the structure. The structure will be only be ... Mehr lesen
When computing ray intensity in 2D axisymmetric models, the wavefront associated with the propagating ray is treated as a spherical or ellipsoidal wave, instead of a cylindrical wave. This tutorial example illustrates how to set up several important features using the Ray Acoustics ... Mehr lesen
In this model, the acoustics of the Small Hall in the Konzerthaus Berlin is simulated with Pressure Acoustics, Time Explicit. This method can take advantage of running on GPUs. A study of the room is performed in the low frequency range. The room acoustic parameters are derived from the ... Mehr lesen
The purpose of this model is to demonstrate pure rolling of a rigid wheel when given an initial forward velocity together with a prescribed lean about this direction. It is assumed that the the rolling motion of the wheel is not affected by contact such that all three components of the ... Mehr lesen
This tutorial shows how to model car cabin acoustics using a low frequency FEM solution concatenated with a high frequency ray solution. The source is a tweeter located in the dashboard corner, which is modeled as a lumped loudspeaker coupled to an electric circuit. To accurately include ... Mehr lesen
Find the optimal cross section areas of trusses in a structure given a prescribed set of limitations and a clear objective. The structure is made up of trusses which are elements that can only sustain axial forces. Mehr lesen
When estimating the parameters of a multiphysics model, both experimental noise and modeling uncertainties will contribute to corresponding uncertainties in the final parameters estimated. In this verification example, we demonstrate the new Variance functionality in the Parameter ... Mehr lesen
