Piezoelectric valves are frequently employed in medical and laboratory applications due to their fast response times and quiet operation. Their energy efficient operation, also dissipates little heat, which is often important for these applications. This model shows how to model a ... En savoir plus
A classic benchmark problem in computational electromagnetics is to solve for the radar cross section (RCS) of a sphere in free space illuminated by a plane wave. This model solves for the RCS of a metallic sphere that has a very high conductivity, which can be treated as a material with ... En savoir plus
In this shape optimization example, the mass of a bracket is minimized by changing the size and position of a number of geometrical objects. The requirements give limits both on the lowest natural frequency, and on the maximum stress in a static load case. This means that results from ... En savoir plus
In this example, the homogenized elastic and thermal properties of a composite material based on a triply periodic minimal surface (TPMS) are computed. A gyroid TPMS-based unit cell is subjected to periodic boundary conditions to get the homogenized material properties. The effects of ... En savoir plus

In this model, sound created by a vibrating piston radiates through a baffled pipe. The impedance is measured and then used in an impedance boundary condition that replaces the surrounding air domain. This technique can be employed to reduce solution time and memory usage for large ... En savoir plus
This example model calculates the bistatic radar cross section (RCS) per unit length of a circle using the Electromagnetic Waves, Time Explicit physics interface. A 2D circle is excited by a 200 MHz sinusoidal signal modulated by a temporal Gaussian pulse. A wideband RCS frequency ... En savoir plus
Thermoelastic damping, which arises when you subject a material to cyclic stress, is an important factor when designing MEMS resonators. The stress brings about deformation, where materials heat under compressive stress and cool under tensile stress. Thus, due to the resulting heat flux, ... En savoir plus
Predicting the transport of solutes that move with subsurface fluids is of general interest in environmental engineering and geosciences. Solutes may not only be pollutants but also artifical tracers added to the groundwater for investigation purposes. This model tracks a solute over ... En savoir plus
A model of a thermal microactuator requires the coupled simulation of electric current conduction with heat generation, heat conduction, and structural stresses and strains due to thermal expansion. The purpose of this model is to demonstrate how to access the cluster computing ... En savoir plus
