How do I calculate element volume weighted average of Nodal results in Mechanical?
The average value given by Mechanical is just an average of all the Nodal results. Therefore, it is extremely dependent on the Mesh. If I have an equidistant mesh then it is correct but for the same if I have fine mesh some regions and coarse in others, the result will be wrong, because more number of sampling points are taken from the fine mesh region. Example - same model, same boundary conditions, different mesh - different results:
