one element different
one element different
(OP)
Hi guys,
I've got a question on something I noticed after doing a calculation. When I look at the results in the contour plot at one location one element displays entirely different than the surrounding ones.
To make myself clearer: I have calculated a contact problem with friction. Then the stresses are displayed and at one spot there is an element that is for example blue (e.g. stress=10N/mm²) while the surrounding elements are red (e.g. stress=20N/mm²). How can that "jump" happen? Do I have to mesh my model finer?
Hope for an answer!
Adios!

There are many options for postprocessing in Viewer that you should explore. Have a look at the menu Results - Options (There's also an toolbox icon for this). You'll see you can turn off averaging, control the different regions used in the averaging and so on. There also an alternative whereby the order of compution of the scalars (before or after averaging) can be set. This will give people an option to make results look more like ABAQUS/POST (!). BTW if there are significant differences in the unaveraged, /POST-like and default /Viewer schemes then you've likely got a mesh that is not refined enough. There is no right or wrong in averaging schemes - it is, after all, averaging!
This is yet another compelling reason to look at the documentation. It is very complete, and will save you from having to say "I'm not sure". I don't believe non-linear FE analysts should ever be satisfied with an "I'm not sure" ;)

I can' get that quite clear.
Hope you can answer me that one too.
