Mesh optimization strategies for solution of engineering problems

Abstract

In this article a new effective adaptive mesh refinement procedure is proposed. Iteration NU,BER IS minimized by using an extended control space notion and a solution improvement strategy near singularities. The possibility to change mesh optimality criteria for error an estimation process is also discussed and analyzed- A numerical example shows that the proposed algorithm is more flexible in mesh gradation control around areas with complex geometry and gives us the most suitable final mesh for domains with singular zones.
