Ansys Optics Fundamental Fridays: What is Multiphysics? In real life, physics don’t happen one at a time. Fluid, structural, thermal, and electromagnetic forces are constantly interacting. It’s where these domains collide that phenomena such as heat transfer, deformation, and mass transport occur. Multiphysics is the analysis of the complex interactions between physical forces through computer simulation. By bringing individual physics solvers together into a single computational framework, multiphysics workflows help engineers accurately model the behavior of an entire system according to how physics happen in the real world — all at once. Multiphysics models fill in the gaps where single-physics analyses are insufficient. Examples of Multiphysics When more than one physic is interacting (such as fluids and structures, or structures and electromagnetics), they are said to be “coupled.” These interactions happen all around us all the time, from tapping the screens on our phones to driving our cars over bumpy roads. Common examples of multiphysics couplings include: ▶️ Thermal-optics Coupling: Heads-up displays (HUDs): Modeling how outdoor temperatures (thermal effects) affect the clarity of projected images in vehicles (optics) ▶️ Fluid-structure Interaction (FSI): Airplane safety: Modeling how airflow (fluid dynamics) affects the deformation and shock absorption (structural mechanics) of landing gear ▶️ Structural-acoustic Coupling: Road noise: Modeling how aural feedback (acoustics) in vehicles is caused by tire-to-surface friction (structural mechanics) ▶️ Electromagnetic-thermal Coupling: Power generation: Modeling how a motor’s energy fields (electromagnetics) produce heat (thermal dynamics) to optimize heat exchangers and fans ▶️ Engineering problems that require multiphysics analysis can be solved with different degrees of coupling. If the physical problem involves a weak coupling of the physics — for example, when fluid forces create structural stress but do not deform the structure significantly — we can solve this with a one-way coupled analysis. If there is strong coupling — for example, if the structure has a high deformation and affects the flow — then we need a two-way coupled solution.

Tech Tip Tuesdays with Ansys Optics: Surface Slope, Surface Curvature, and Phase Slope Analyses Improvements Easily analyze and constrain the maximum slope or curvature across a surface or diffractive to ensure manufacturability. With the 2024 R2 Release of Ansys Zemax OpticStudio, users can now easily analyze the maximum surface slope, maximum surface curvature, and maximum phase slope using the new "Modulus" data type in the settings of the respective analyses. The Modulus will return the maximum value of the slope or curvature, regardless of the direction of the vector. This new data type was also added to the respective cross section analyses. This new data type is also available now for several Merit Function Operands: SSLP, SCRV, and PSLP return the value for the maximum slope or curvature at a specific point on the surface, while DSLP, DCRV, and QSLP apply to the entire surface. These operands ensure the manufacturability of your system, e.g. constraining the maximum phase slope during optimization to keep the width of DOE lines to manufacturable values or constraining the maximum surface slope so that sag can be correctly measured interferometrically. Join our webinar on September 12th to learn more about this update and all the features included in the Ansys 2024 R2 Release of Ansys Zemax OpticStudio, Ansys Speos and Ansys Lumerical.

Did you hear about the new Ansys Speos Live Preview Virtual Lighting Controller?? Continue your result experience journey with Live Preview thanks to the new capabilities accessible from its intuitive user interface. Live Preview offers the possibility to individually control light sources as a post processing of the result, with Virtual Lighting Controller. Sources can be tuned individually or by group at once, entering numerical values or using the slider. Light levels are instantaneously updated, without restarting the GPU simulation. Lighting configurations can be created and used during simulation. Those configurations are also kept when exporting the result as a xmp file. Combined with interactive update, users can considerably reduce the number of simulations to launch and rely more on immediate memory in their design process. Join our webinar on September 12 to learn more about Ansys Speos Live Preview updates and explore all the latest features in the 2024 R2 Release of Ansys Zemax OpticStudio, Ansys Lumerical, and Ansys Speos.

Did you know that you can simulate lasers with external passive microring resonator circuits and narrow (sub-MHz) linewidths using Lumerical and include advanced physics effects such as mode hopping? The evolution of lasers is moving towards lasers with widely tunable frequency range and narrow linewidths. This could be achieved by coupling the optical gain medium to external low loss passive optical resonator circuits with larger resonator lengths and frequency selectivity. Using microring resonators in the passive circuit offers advantages such as simpler fabrication compared to alternatives like Bragg gratings, longer optical paths due to multiple round trips in the microring, and efficient frequency tunability. The frequency tunability of microrings enables widely tunable lasers, while the longer effective resonator length enables narrow linewidths. Leveraging our advanced Travelling Wave Laser Model (TWLM) in INTERCONNECT, we created a new application gallery example demonstrating accurate simulation of these types of lasers and effects. And thanks to our recent Optical Frequency Noise Spectrum Analyzer (OFNSA) model in INTERCONNECT, it is also possible to measure extremely narrow linewidths in a computationally efficient way.
