WebIt is important that you use a sufficiently refined mesh to ensure that the results from your Abaqus simulation are adequate. Coarse meshes can yield inaccurate results in analyses using implicit or explicit methods. The numerical solution provided by your model will tend toward a unique value as you increase the mesh density.

Web15 Apr 2016 · Situation #1 : The form of the solution is unknown prior to solving. In areas of high pressure, temperature, or velocity gradients, it’s necessary to refine the mesh for higher accuracy. In some cases, intuition can predict where those areas may be but, in complex cases, it’s impossible to know in advance. Web1 Dec 2011 · Abstract A scheme is presented for constructing refined regions of 2D unstructured computational meshes composed of triangular cells. The method preserves the conforming property of the original unrefined mesh and does not produce hanging nodes.
