Selective Laser Melting (SLM) offers great potential for future manufacturing technology. In order to extend its applicability for the processing of high melting materials like molybdenum fundamental process understanding is required. This can be obtained by multiphysical simulations ... 詳細を見る

An extension of the Solid Mechanics interface in COMSOL Multiphysics® is presented to analyze localized deformations of quasi-brittle materials, for example cracking in concrete. This is achieved by implementing an isotropic damage mechanics constitutive law, which is combined with both ... 詳細を見る

Time-dependent multiphysical simulation of pulsed and continuous laser welding of dissimilar metals, based on Moving Mesh (ALE) approach, is proposed. Strong coupling between heat transfer, laminar compressible flow and ALE is used. The model was validated for a case of single ... 詳細を見る

The US Food and Drug Administration (FDA) faces significant challenges in its regulatory approval processes due to a lack of relevant science, and many practices are limited by laws enacted in the previous century [1]. Therefore, in recent years, the FDA has identified the need for ... 詳細を見る

As the flow passed through the pipe, and entered the bend, various vortical structures appear, meaning that there is a secondary flow emerging. Also while the flow is in the bend gravity forces affect distinctively its behavior as long as the centrifugal force is not greater. From this ... 詳細を見る

Microarrays are extensively used in modern biology as tools of multiplexed, high throughput analysis to study thousands of genes and their expression inside cells at once [1]. The basic principle of a microarray is quantitative detection of fluorophore tagged DNA. Use of this method ... 詳細を見る

We show that COMSOL Multiphysics® software can efficiently simulate the diffusion equation (DE) in diffusive optical tomography systems. Using our implementation, we simulate a frequency domain diffusive optical tomography system two order of magnitude faster than the standard Monte ... 詳細を見る

Single-phase fluid flow was simulated passing through various three dimensional pipe elbows. The simulations varied by Reynolds number, curvature ratios, and sweep angles and were all conducted using the k-ε model available in COMSOL Multiphysics® software. The intent of this research ... 詳細を見る

Stimulated Brillouin scattering (SBS) is a nonlinear phenomenon coupling optical and elastic waves. Traditionally regarded as an undesirable side-effect, it has garnered renewed interest as a platform for investigating slow light, nonreciprocity, and for designing high-performance chip ... 詳細を見る

Interstitial photodynamic therapy (I-PDT) can be applied for the treatment of locally advanced head and neck squamous cell carcinoma (LA-HNSCC). The complex anatomy of LA-HNSCC requires careful planning of the light delivery and fiber insertion. We have developed an image-based approach, ... 詳細を見る
