This tutorial analyzes the hysteresis of the conductance-gate-voltage (G-Vg) curves of an InAs nanowire FET, using the density-gradient theory to add the effect of quantum confinement to the conventional drift-diffusion formulation, without a large increase of computational costs. The ... Mehr lesen
This model demonstrates how a nonlinear equation system can be setup to solve for the eigenfrequencies of a symmetric laser cavity. The model uses the bidirectional formulation of the Electromagnetic Waves, Beam Envelopes physics interface. The computed eigenfrequencies are verified with ... Mehr lesen
This model demonstrates the polarization properties for a Gaussian beam incident at an interface between two media at the Brewster angle. The model shows how to use the Electromagnetic Waves, Beam Envelopes physics interface with a User defined phase specification. Matched Boundary ... Mehr lesen
This tutorial model solves the Gross–Pitaevskii Equation for the ground state of a Bose–Einstein condensate in a harmonic trap, using the Schrödinger Equation interface in the Semiconductor Module. The equation is essentially a nonlinear single-particle Schrödinger Equation, with a ... Mehr lesen
This tutorial shows how to set up a ray release based on the incident electric field at a boundary. First the Electomagnetic Waves, Frequency Domain interface is used to solve for the electric field of a plane wave. Then rays are released with initial intensity and polarization matching ...

A plane wave is incident on a reflecting hexagonal grating. The grating cell consists of a protruding semisphere. The scattering coefficients for the different diffraction orders are calculated for a few different wavelengths. Mehr lesen
Real reactors can be modeled as combinations of ideal reactors. In this example the so-called "Dead zone model" is utilized. Two ideal CSTRs with interchange are set up to model the real reactor. One CSTR represents the highly agitated region and the other the less agitated region. For ... Mehr lesen
Eine Helmholtz-Spule ist ein paralleles Paar identischer kreisförmiger Spulen, die einen Radius voneinander entfernt und so gewickelt sind, dass der Strom durch beide Spulen in dieselbe Richtung fließt. Diese Wicklung führt zu einem gleichmäßigen Magnetfeld zwischen den Spulen, wobei die ... Mehr lesen
A Hall effect sensor is a semiconductive material with an anisotropic conductivity that is a function of the magnetic field. A magnet, mounted on a wheel, is rotated around nearby the sensor and the variation in the electric potential across the sensor is modeled. For complete ... Mehr lesen
Seawater intrusion is a critical issue in coastal regions, where it endangers both freshwater supplies and the overall quality of groundwater. This example showcases seawater intrusion in a coastal aquifer where a pumping well is located at some distance from the shoreline. The model ... Mehr lesen
