A multiplicative Schwarz method with active subdomains for transient convection-diffusion problems

An efficient algorithm to find the solution of transient convection–diffusion problems with dominant convection is presented. The main idea is to follow the solution front and activate those subdomains where the solution satisfies a given threshold value. We call this novel method ‘the multiplicativ...
