Getting to Market: Product Design and Development After providing proof of concept for a new medical technology, device or development of second-generation devices, the next step is finalizing the product design. This is one of the most important stages in the development of a successful medical device since a flawed design may lead to it being […]

At virtually every step of the model creation process, you need to select and apply materials, physics boundary conditions, and other settings to your model geometry. Bookkeeping of these settings can be challenging, especially when you re dealing with large, complex geometries and multiple physics interfaces. In COMSOL Multiphysics, Selections provides a tool to organize your model

Proof-of-Concept: In the Beginning There Was… Innovative product concepts and technologies invariably need to provide some level of Proof of Concept before an organization or agency will commit significant investment in money and/or resources to support continued development and commercialization. PCM&S is being increasingly used during the proof-of-concept phase to demonstrate technical feasibility, identify critical

Introduction Medical devices continue to provide a crucial component in the diagnosis, prevention, monitoring, and treatment for diseases. Unlike drugs or biologics, a medical device can vary from the simple, which poses little or no risk to the user such as a tongue depressor or toothbrush, to the life-sustaining such as a pacemaker or medical

Developing solutions using Computational Fluid Dynamics (CFD) often challenges simulation engineers. These simulations may require long computational times and large amounts of computer memory. AltaSim regularly solves complex CFD problems and finds that meshing is a critical component for run-time and computer memory issues. To help you solve your CFD problems with less frustration and

As COMSOL Multiphysics evolves, methods to include important features in simulations change. Coupling temperatures to different physics is a common need for multiphysics simulations. COMSOL has made changes that effect temperature coupling. Our clients have asked about the warning signs they get when using temperature coupling, and we would like to share with you our

Background Consistent behavior of high-performance optical structures requires maintenance of structural stability over the range of potential operating conditions. In practice, thermally induced aberrations are ubiquitous in optical systems and can limit the performance of optical devices such as gravitational wave detectors, deformable mirrors, lithographic systems, high power lasers, space optical instruments and telescopes, optical
Making accurate physics predictions using simulations requires a knowledge of the material properties and how to implement them correctly in the software. This is particularly important in analyses involving thermal expansion when the coefficients of thermal expansion (CTEs) of the materials vary significantly with temperature. For example, optical devices that operate in the vacuum of

Incorrect boundary conditions in finite element analysis (FEA) lead to incorrect solutions, or the simulation does not converge. To develop a converged solution, all FEA models require constraining each dependent variable somewhere in the model. Typically, this is done directly onto the model region geometry, but it can also be accomplished through Robin conditions. This

Post processing is the last of the five primary steps of simulation development. This step represents the payoff from all the hard work of the previous steps, and it drives the deeper understanding of the design that engineers obtain though simulation. A simulation engineer can significantly improve their understanding, and better communicate that understanding, when
