DescriptionA working simulation is not a confirmation that your fabricated prototype will work! The numbers you get from a simulation are not necessarily close to those measured! A simulation only approximates the real behavior and neglects many real phenomena! If the previous statements are true (and they are), why bother to take this course? Well, the above statements are true for complex multiphysics problems. For relatively simple problems (usually single physics or for structural and thermal problems), the results obtained from the model and the measurements usually agree well with each other. However, for computationally-intense problems that are multiphysics in nature, results can vary significantly. Yet, the reason for creating the model is to obtain an idea about the general behavior of the system, get a 'feel' of what happens when different parameters change, observe how severely different inputs affect the output, help in optimizing, or rule out materials, geometries, etc., that most probably will not work. With this in mind, we can see that simulation plays an important role in saving time (which means you graduate faster!) and in saving money. This tutorial will give you a jump start on COMSOL and help you in research. Irrespective of what your area of research is, be certain that COMSOL can be of value. We will learn how to create geometries, create meshes and refine them, impose boundary conditions, apply a few tricks to help get more accurate results, and generate appealing figures that will make your next publication prettier (which will help the reviewer make a decision in your favor!).
Dr. Amro M. Elshurafa received his BEng (with distinction), MASc, and PhD degrees all in electrical engineering from Dalhousie University, Halifax, Nova Scotia, Canada, in 2002, 2005 and 2008 respectively. During his graduate education, Dr. Elshurafa was the holder of the prestigious Canadian Network of Centers of Excellence on Microelectronics (MICRONET) scholarship during the academic year 2007-2008 which is funded by the Federal Government and Industry of Canada. He was invited to write an application note to the Canadian Microelectronic Corporation (CMC Microsystems) regarding the compatibility between L-Edit and COMSOL, which later became a most downloaded document for two consecutive months in 2008. His journal paper published in the IEEE Journal of Microelectromechanical Systems (JMEMS) in February 2012 introducing RF MEMS Fractal Capacitors has also been among the top 10 most accessed articles in March 2012 for JMEMS. Further, his research published in the Journal of Micromechanics and Microengineering was also featured on High Beam Research and Electronics Newsweekly. He is the author of nearly 30 publications and patents. A certified six sigma black belter, an ISO9000 certified internal quality auditor, Dr. Elshurafa is a registered professional engineer in the province of Nova Scotia, Canada. Immediately following his PhD, Dr. Elshurafa joined the Sensors Lab at King Abdullah University of Science and Technology (KAUST), Thuwal, Saudi Arabia, as a post doctoral fellow where he still remains.
