The room was abuzz with engineering students from across the country at the 12th annual conference of Comsol. Students were bent over their laptops creating models on Comsol’s multiphysics software. This was the view in the training rooms during the Comsol conference organised on 20 & 21 October in Bangalore. More than 200 attendees from different industries and academic institutions made their way to the event. The conference programme included 28 mini training courses.

Roping in the industry, the keynote speakers demonstrated real-time industry application of the software. For instance, for the two-wheeler segment, noise control involves the evaluation of different parts of the engine and exhaust system based on various acoustic criteria.

“The Acoustics Module, an add-on product to Comsol Multiphysics, is used to evaluate the acoustic performance of engine and exhaust systems against the various criteria. To meet the acoustic criteria, modifications are then made to the system design,” said Gyanendra Roy, CAE head from Mahindra Two Wheelers Limited (Pune), giving his keynote on motorcycle noise and sound analysis. Another keynote focused on terahertz (THz) optical element designs for spectroscopy applications. “Although there are several Comsol Multiphysics modules that can be of use for design purposes, we use the Wave Optics Module for our applications to fabricate different THz frequency polarizers, filters, metamaterials and THz spectroscopy setups. Simulation helps save a lot of time on the fabrication of components by identifying design errors,” said Dr Shriganesh Prabhu, who earned his PhD from Tata Institute of Fundamental Research.

Solutions for chemical engineering

The Chemical Reaction Engineering Module in Comsol Multiphysics has customised functionality for the analysis of chemical systems primarily affected by chemical composition, reaction kinetics, fluid flow and temperature as functions of space and time. It has several interfaces to model chemical reaction kinetics; mass transport in dilute, concentrated and electric potential affected solutions; laminar and porous media flows, and energy transport.

Some of the user presentations for the CRE modelling were from the Advanced Technology Development Centre and School of Medical Science and Technology at (IIT) Kharagpur; Dept. of Cardiology, Medical College and Hospital, Kolkata; and Department of Chemical Engineering, Indian Institute of Science, Bangalore.

Academic attendees

The conference showcased about 75 user presentations in the form of posters and oral presentations. Engineering students from Indian Institute of Technology - Kharagpur, Delhi, Chennai, Bhubaneswar, Roorkee, Rupnagar and Varanasi took part for the user presentations among others. Also, international user presentations were from; Manipal University, Dubai, UAE; University Of Science Malaysia (USM), Georgetown, Penang, Malaysia; Institute of Tele. Radioelectronics and Electronic Engg, Lviv Polytechnic National University, Lviv, Ukraine; Nordita, Stockholm, Sweden; and RCAST, The University of Tokyo, Japan. The best paper award went for Subhashish Dasgupta from ABB, Bangalore, while Biju AF from Honeywell Bangalore won the best poster award.

As part of the conference, attendees voted for their favourite poster. Thennavarajan Subramanian from NAL won the best poster in this category.

All in all the two-day Comsol conference saw both the industry and academia working and learning together. Added to that, the conference ended on a hopeful note, with a promise of more to come in the next few years.

Comsol introduces latest software update at the Conference

Comsol Inc product managers unveiled the latest version of Comsol 5.2a at the 12th annual conference series. The updates of Comsol Multiphysics software, Comsol Server product and Comsol Client were introduced. The Comsol software features major performance increase and release of the Rotordynamics Module, which is now available as an add-on product to the Structural Mechanics Module.

The speedup is most notable with respect to the handling of models with several thousand domains and boundaries, for the latest update. Comsol is committed to delivering the most efficient and robust multiphysics environment for its wide range of products for electrical, mechanical, acoustics, fluid, thermal, and chemical simulations.

“To fulfil this commitment, Comsol’s development team ensures that each update of the Comsol software provides more efficient solvers, meshing, and physics modelling functionality,” commented Bjorn Sjodin, VP, product management, Comsol Inc. Comsol showcased examples of how customers are leveraging simulation apps to enable company-wide usage of multiphysics simulation.

“These case studies provide us with a first look at how our customers benefit from building and deploying simulation apps,” said Svante Littmarck, president and CEO, Comsol Inc, in his keynote presentation. “The Application Builder and Comsol Server™ are the tools that organisations need in order to provide multiphysics for everyone.”

The latest update of the new Rotordynamics Module will aid engineers in analysing vibrations due to centrifugal forces and other gyroscopic effects in rotating machinery. This new product will be used to ensure that rotor vibrations are contained within acceptable design limits. This module will be of particular interest to those working with the design of turbines, turbochargers, electrical machinery, and pumps in the automobile, marine, aerospace, energy, and household appliance industries.

“With the Rotordynamics Module, users can take into account the effects of various components such as disks, bearings, and foundations,” explained Prashant Srivastava, a technical product manager at Comsol.
