The College of Education for Pure Sciences at the University of Basrah organized a scientific lecture entitled “The Weak Corner Method for Solving Pregnancy and Diffusion Issues”.
The lecture presented by the researcher (Ibtihal Ahmed Abdel Nehme) included
This lecture dealt with the presentation of some important concepts and studies in the 'finite element method'. The weak corner finite element method was described as a method for solving load and diffusion issues. This method is considered one of the most efficient methods, but when it is adopted in problems whose first derivatives contain large coefficients (controlled by convection). Difficulties such as fluctuation and instability as a result of the load limit controlling the spread limit. We will use the artificial diffusion method to treat the fluctuation, and then we will use the diffusion method towards the streamline function to treat the defect that occurred in the artificial diffusion method. After that, we will study all the properties of the numerical solution using the Wick method from the law of conservation of energy, stability, the greatest principle, and convergence.
