A posteriori error estimate for an emf in a 2d boussinesq type model
(Sello Editorial UNAD, 2022-11-25)This work studies the numerical approximation of the solution of a non-linear 2D Boussinesq type system, where we implement a posteriori error method for the automatic refinement of the finite element method mesh to reduce the error in the approximation. In previous works, the existence and uniqueness of solutions for this type of system has been studied (Mejía & Muñoz, 2021; Chen, 2009). In this continuation of ... -
System Design For The Circular Economy Process Of Recycling Workers
