I am new to COMSOL. I want to implement a nonlinear transient multi-physics problem employing weak form. Can somebody introduce me a textbook or a tutorial? A solved example will be of very helpful.
Hi Mohammad, in Comsol a specific pack for this kind of modelling is available. The tool is called Mathematics and is part of the so called equation-based modelling approach.
With this Comsol option it is possible to define weak formulations, weak constraints, weak contributions as well as define and solve systems of ODE, PDE and DAE.
For the applicative part, I suggest you the video tutorials about PDE that are available in the support page of the Comsol website.
With respect to the theoretical part, instead, in my opinion a good reference is :
Multiphysics Modeling Using COMSOL: A First Principles Approach. By Roger Pryor.
