Good agreement of the model results with experimental data was established to provide a basis for reasonable service life prediction in view of the time-to-corrosion initiation paradigm. Simulations of the problem in COMSOL allow main process of the chloride binding to be closely captured in the light of its nonlinear concentration dependence and influence on evolution of chloride diffusivity governing the transport problem. The aim of this work is to demonstrate the capability of using COMSOL Multiphysics modeling to provide insight regarding a more realistic consideration of chloride penetration behavior in concrete in view of chloride binding.

To permit a more realistic modeling of the diffusive transport of chloride in concrete, chloride binding capacity model based on experimental isotherm describing the relation between total, bound, and free chlorides have to be considered. One of the most revealing causes of deterioration leading to durability loss in concrete structures is premature time-tocorrosion ignition due to chloride induced corrosion associated with diffusive transport of chloride in concrete.
In this regard, treatment of the time-to-corrosion initiation problem is decisively done in a manner averse to unrealistic assumptions of constant diffusivity associated with null binding often enforced for solution expediency. Underlying effort of this paper is therefore to demonstrate the use of COMSOL Multiphysics Software, an interactive 3D-partial differential equation development and simulation environment previously known as FEMLAB, in effectively solving the diffusive transport of chloride in concrete. of Petroleum & Minerals, Saudi ArabiaĪbstract chlorides ingress in concrete under field service conditions is often ignored for formulation and analytical difficulty reasons. of Petroleum & Minerals, Saudi Arabia 3 Research Institute, King Fahd Univ.

We welcome user feedback and feature requests for future software releases - whether during a panel discussion at the COMSOL Conference, a one-on-one conversation with a staff member at a workshop or COMSOL Day event, or through email or social media. We are grateful for those who voted for COMSOL Multiphysics as Product of the Year, and we are also grateful for everyone who uses it. Linda Bell, editorial director at Tech Briefs, recalls that this year’s voters were especially intrigued by COMSOL Compiler™, a product for compiling simulation applications into standalone, executable files that can then be distributed for use by anyone in the world.Ĭompiled applications can be easily distributed to anyone, anywhere. User-Driven Features and a Focus on Democratizing SimulationĬOMSOL Multiphysics version 5.4 provides users with two new products, COMSOL Compiler™ and the Composite Materials Module, as well as various performance enhancements and new features. At the end of the year, the magazine invited its readership to cast their votes for the product of the year out of the top products from each month - and COMSOL Multiphysics was chosen. Version 5.4 of the COMSOL Multiphysics software, which was released in October 2018, had previously been recognized as Tech Briefs‘ November Product of the Month. Linda Bell, editorial director of Tech Briefs magazine, presents Daniel Smith, product manager at COMSOL, with the Readers’ Choice Product of the Year award. Daniel Smith accepted the award on behalf of our Development department. Last week, Linda Bell and Ed Marecki from Tech Briefs presented COMSOL with the award at our Burlington office.
Recognition from Tech Briefs Magazine as Product of the YearĬOMSOL Multiphysics was announced as one of the three Product of the Year winners in March 2019. Therefore, the celebration would not be complete without raising a glass to you. Since many software features come directly from user feedback and requests, COMSOL Multiphysics users themselves are a driving force behind the award. Last week, Tech Briefs magazine presented COMSOL with the award at our Burlington, MA, office - complete with a champagne toast. In 2018, COMSOL Multiphysics® version 5.4 was chosen as a Tech Briefs magazine Readers’ Choice Product of the Year.
