Mesh Convergence

One way to check the accuracy of the simulation is to refine the mesh and re-run the simulation. The smaller the element in the mesh, the more accurate the simulation will be. The only drawback is longer computation time. To refine the mesh, insert Body Sizing on the specimen and set the element size to 0.001m. Also, enter 0.002m for the element size in the Details of "Mesh". The original mesh has 620 Elements and 4533 Nodes and the new mesh has 1600 Elements and 11204 Nodes.

The net radiation shows very little change as the number of elements is doubled. No further mesh refinement is need.
