Stress Analysis of a Portal Crane

Portal Cranes are common when handling heavy loads. In this example, the Beam interface is used to compute the stresses in a portal crane designed for lifting 15 tons. Three load cases are considered: self weight, payload, and thermal expansion on a hot summer day. An internal hinge ... En savoir plus

Broadband Optimization of Microstructured Antireflecting Coating

This model showcases the broadband optimization for the Microstructured antireflecting coatings that are modeled in the model (#99011). Following are the parameters that are optimized: Rectangular microstructure: Height and width of the rectangular microstructure. Pyramidal ... En savoir plus

Sensitivity Analysis of a Truss Tower

Sensitivity analysis is an efficient way of computing the gradient of an objective function with respect to many control variables. This example uses the pitch and yaw in the top of a truss tower as objective functions. It shows how to compute the sensitivity of these angles with respect ... En savoir plus

Adsorption-Desorption Voltammetry

For an electrochemical reaction to occur, the reacting species usually needs to adsorb to the electrode surface before undergoing reduction or oxidation, after which the resulting product species desorbs back into the electrolyte. If the rate of adsorption or desorption is slow in ... En savoir plus

Lossy Circular Waveguide

In mode analysis it is usually the primary goal to find a propagation constant. This quantity is often, but not always, real valued; if the analysis involves some lossy part, such as a nonzero conductivity or an open boundary, the eigenvalue is complex. In such situations, the real and ... En savoir plus

Axisymmetric Cavity Resonator

This is a benchmark model for the 2D axisymmetric formulation of the Electromagnetic Waves, Frequency Domain interface that is available with the RF Module. The problem is to find the resonant frequencies and fields inside an axisymmetric cavity with rectangular cross-section and ... En savoir plus

Slot-Die Coating with Channel Defect

This is a tutorial of a slot die coating process in 3D where the channel is obstructed. The example uses a two-phase flow phase-field method with a non-Newtonian power-law fluid. The effects on the film thickness of the channel obstruction can clearly be seen. En savoir plus
