Abstract:

Numerical modeling of heat conductivity in 3D is complex and time consuming issue. Mesh adaptation is one of the methods which shortens calculations time in comparison to solution on dense mesh and gives exact results, in comparison to coarsen mesh, through refinement of the mesh depending on problem type and boundary conditions. In this paper mesh discretization error is evaluated and authors present the influence of the mesh adaptation process on modeling on the example of heat conductivity. Experimental results show that mesh adaptation leads to more accurate and suited models of the physical phenomenon.
