This example uses the thermal expansion of a laminated composite shell model to demonstrate the use of the feature Thermal Contact, Interface, applied on interfaces between layers in a laminated composite shell. The first study is computed neglecting this additional thermal resistance in ... En savoir plus
This model analyzed the ALD deposition process of alumina film on the surface of a U-shaped structure. In this process, gaseous precursors are sequentially introduced to the reaction chamber and sequentially undergo a series of adsorption and chemical reactions on the surface. The ... En savoir plus
Opto-acoustophoresis is a term used to describe the interplay between acoustics and optical fields. In most cases (including this) the optical field is heating up the material and therefore affecting the acoustic field. In this example of an acoustic trap a set of particle are trapped ...

Chemical mechanical polishing (CMP) is a crucial technique for surface planarization, widely used in semiconductor fabrication and optical device manufacturing. This model simulates the flow field within the CMP retaining ring and tracks the motion of abrasive particles carried by the ... En savoir plus
This benchmark model computes the load-carrying capacity of a one dimensional hydrodynamic step bearing. The results are compared with analytic expressions obtained by solving the Reynolds equations directly in this simple case. En savoir plus
The model demonstrates the basics of the 3-omega method. The coupled electromagnetic heating problem is solved in a solid sample which is heated by a thin copper strip, deposited on the surface of a sample. Analyzing the frequency dependence of the voltage oscillation amplitude, we ... En savoir plus
This example compares moisture transport within two types of anisotropic porous medium. The first component defines a layered structure. The structure alternates between layers with high and low moisture diffusivity. So the moisture spreads more easily along the layers than transversely. ... En savoir plus
When designing oxygen masks for delivering respiratory support to patients via BiPAP and CPAP, multiphysics modeling helps visualize the flow pattern inside the mask for a given design. From there, it is possible to estimate oxygen consumption, carbon dioxide accumulation, and ... En savoir plus
This example studies heat transfer in a square column. Cold and hot temperature conditions are applied to the boundaries. Due to the symmetry of the problem, the geometry is simplified to half of the square. The temperature field is compared with the analytic data. This example ... En savoir plus
In this example, a heat transfer model of a fiber composite's unit cell is analyzed with the Cell Periodicity feature. The homogenized thermal conductivity, density and heat capacity of a composite material are computed based on the individual properties of fiber and matrix. A comparison ... En savoir plus
