COMSOL Multiphysics software program is among the most dear software program modeling instruments for engineers and scientists. This e-book is designed for engineers from the fields of mechanical, electric, and civil disciplines, and introduces multiphysics modeling ideas and examples observed via functional functions utilizing COMSOL 4.x. The publication contains a significant other CD-ROM with records of over 25 types, photos, and code. the most goal is to introduce readers to exploit COMSOL as an engineering device for modeling by way of fixing examples which may turn into a consultant for modeling related or extra complex difficulties. the target is to supply a suite of examples and modeling guidance in which readers can construct their very own types. Readers are assumed to be acquainted with the rules of numerical modeling and the finite aspect strategy (FEM). The ebook takes a flexible-level process for featuring the fabrics in addition to utilizing useful examples. The mathematical basics, engineering ideas, and layout standards are provided as fundamental elements of examples. on the finish of every bankruptcy are references that comprise extra in-depth physics, technical info, and knowledge; those are noted in the course of the ebook and utilized in the examples. COMSOL for Engineers will be used to enrich one other textual content that offers history education in engineering computations and strategies. Examples supplied during this e-book can be regarded as "lessons" for which history physics might be defined in additional aspect. FEATURES

Between the parameters of the CAD geometry in COMSOL and update it if needed. The LiveLink modules make the CAD package an integral part of COMSOL. These modules enable users to run COMSOL from the interface of a CAD package. LiveLink modules are extremely useful and are recommended for users who have more complex model geometry and would like to use their favorite CAD package for building them. In addition, users can import a solid model in conventional format such as Parasolid, STEP, IGES, VRML, and STL.
We would like to calculate the displacement and stress field in the plate resulting from the applied loads. 4 in, and applied tension stress load is 500 psi at the right-middle edge. 3. The boundaries on the left side of the plate are constrained while the other plate sides are let free. 1 Geometry, dimensions, and boundary conditions. Solution 1.
