SOLIDWORKS Simulation: Energy Norm Error Plots
In this article, we are going to be taking a look at a Simulation Results plot that helps to determine if you have sufficiently refined the mesh in critical areas of your model. The plot is called the Energy Norm Error and it is a type of Stress plot. The Energy Norm Error plot tells you how much error there is in the stress and strain values in individual mesh elements. To reduce error you can refine the mesh, but as always, you will want to save the most extreme mesh refinement for areas of interest, such as high-stress spots.
