FEA and CFD based Simulation and Design for Medical and Biomedical Applications

FEA and CFD based Simulation design and analysis is playing an increasingly significant role in the development of medical devices, saving development costs by optimizing device performance and reliability, reducing benchtop tests and clinical trials, and helping to speed the regulatory approval process. Developing increasingly complex medical devices requires increasingly capable tools for simulation and testing. Our deep portfolio of simulation and testing solutions allows medical device developers to generate digital evidence of device performance across a range of engineering disciplines, throughout the product life cycle. Medical applications are typically subjected to a wide range of complex environmental and biological loading conditions.The variability of these conditions makes the physical testing of all possible scenarios both difficult and time-consuming. By using FEA and CFD multidisciplinary and multiphysics simulation technology, our engineers can study a greater number of real-world design behaviors with higher accuracy.

As part of our promise to excellency, we have experts with FDA's guidance for Reporting Computational Modeling and Simulation (CM&S) Studies in Medical Device Submissions.

Enteknograte engineering team use advanced CAE software with special features for mixing the best of both FEA tools and CFD solvers: CFD codes such as Ansys Fluent, Siemens StarCCM+ and FEA Codes such as ABAQUS, Nastran, LS-Dyna and the industry-leading fatigue Simulation technology such as Simulia FE-SAFE, Ansys Ncode Design Life to calculate fatigue life and MSC Actran and ESI VA One for Acoustics and VibroAcoustics simulations.

With combination of deep knowledge and experience in sophisticated FEA and CFD based simulation and design tools and coupling with 1D System modeling Software such as Matlab Simulink, Enteknograte engineers can solve any problem with any level of complexity in Medical and Biomedical applications Design and Optimization.

Digital Twin for Orthopedics, Dental and Medical Device Industry

Our solution portfolio provides an open, integrated environment for device development, manufacturing, and service of orthopedic and dental devices. Our proven solutions ensure device quality, traceability and regulatory compliance across the lifecycle. The key differentiators of our portfolio and engagement strategies for medical device manufacturers are Digitalization, Realization and Simulation. Digitalization: “Digitalize” across the multi-disciplinary, software and hardware mechatronic domains, utilizing our data-centric approaches and automation, instead of document-centric procedures, thereby creating Digital Twins and Digital Threads, making product and process knowledge explicit, accessible, and re-usable.

Realization: Great ideas are nice, but ideas have little value until they can be transformed them into “realized” manufactured devices with high quality, and high confidence in their ability to perform safely and effectively in the healthcare delivery value chain. Simulation: Digital Twins predict and optimize the operating performance of your devices, as well as manufacturing and service operations. Work out quality and volume production ramp-up issues early, digitally, and avoid expensive rework driven by late stage non-conformances and complaints

FEA Analysis of Orthopedic Implants

Multidisciplinary simulation provides a methodology for the analysis of complex engineering systems and subsystems, exploiting the synergism of mutually interacting phenomena such as thermal and structural loading. Multidisciplinary analysis also enables the chaining of analysis sequences so that the output state of one sequence can be used as the input state for the next. Multidiscipline simulation solutions for medical device tests include:
