Recent advances in the use of remote labs in fluid mechanics
Published in Ataur Rahman, Vojislav Ilic, Blended Learning in Engineering Education, 2018
COMSOL Multiphysics: COMSOL Multiphysics is a finite element analysis–based multiphysics simulation software. This software has a built-in model builder which can extend one type of physics model into multiphysics models and vice versa. This software allows the user to design a model by defining relevant physical quantities such as loads, constraints, material properties, sources and fluxes, which eliminate the need for the underlying equations. These variables can be applied to solid or fluid domains independently of the computational mesh. COMSOL can be used as a standalone black box simulation software or users can program their own simulation by coding with Java or MATLAB. The simulation can be carried out in various fields of science and engineering including fluid dynamics, heat transfer, microfluidics, photonics and quantum mechanics (COMSOL, 2012).

There are many CFD-based commercial software that can be used for solving heat and mass transfer process in porous media. Among them COMSOL Multiphysics (Comsol Inc, www.comsol.com), FLUENT (Fluent Inc, www.ansys.com), ANSYS (Ansys Inc, www.ansys.com), CFX( Ansys Inc, www.ansys.com), STAR-CD (CD Adapco Group, www.cd-adapco.com), PHOENICS(CHAM Ltd, www.cham.co.uk) and ADINA (ADINA Inc, www.adina.com) are popular. COMSOL Multiphysics is a multi-disciplinary, advanced simulation software for modelling and simulating physics-based problems. This software is very user-friendly and can easily account for coupled or multiphysics phenomena involving various physics such as electrical, mechanical, fluid flow and chemical applications. As COMSOL can easily implement material properties and input parameters as a function of independent variables, it is very useful in drying application because the material properties change with temperature and moisture content during drying (Khan et al. 2016b). Recently, many researchers have used this software to efficiently implement their model in drying (Curcio 2010, Dhall et al. 2012, Khan et al. 2016b, Kumar 2015, Kumar et al. 2012a, 2015, 2016a,c, Perussello et al. 2014, Zhang and Kong 2012). Kumar et al. (2015) used COMSOL Multiphysics for simulating convection drying and intermittent microwave convective drying (IMCD). Their solution procedure using COMSOL Multiphysics is shown in Figure 8.10.
Modelling the electroforming process: significance and challenges
Published in Transactions of the IMF, 2021
COMSOL Multiphysics® is a simulation software that uses finite element analysis to solve numerical and design problems deriving from any engineering sector, especially those involving modelling of physics, acoustics and fluid dynamics. COMSOL includes an electrodeposition module which can be employed for electroforming simulations. COMSOL Multiphysics® retains the reactor ‘creation’ by the user or via importation of CAD models. The software interface makes it easy to declare the reactor’s boundaries and initial parameters, insert material characteristics, as well as monitor and control various parameters.

COMSOL Multiphysics is a finite element-based simulation software which can be used for a vast range of physics. The use of COMSOL Multiphysics (heat transfer module) to simulate asphalt cooling behaviour has been reported in the literature (Sheeba and Rohini, 2014; Dan et al., 2017; Dong et al., 2019; Sun and Sheng, 2019). In the present study, the asphalt layer is modelled as a 1-D element in the heat transfer module of COMSOL Multiphysics 5.4 (COMSOL, 2019) to simulate asphalt cooling behaviour during compaction.
