. you explained so well when the 'Average across bodies' should be used and when not. And also, in which case 'Nodal Difference' option can prove to be fruitful. But I didn't understand one thing, if you may. For example, I see a huge step between few elements' boundaries using the 'Nodal Difference' option. You mentioned that the size of the mesh should be improved. But what is the goal of doing this? I mean what would I achieve in doing so?nSecondly, the option 'Nodal Difference' and 'Elemental Difference' are used side by side, or they each have a particular purpose. You described the purpose of Nodal difference, what about Elemental Difference? nThank you.n
