Hello,

For my simulations I'm interested in contact pressures. I need to make some changes to the values for every increment and each node, therefor I use a subroutine in which I write the contact pressures for each node in contact to a file.
The values I get from the user subroutine are however different from the values I see in the visualization module. The difference can be quite large in some cases up to 20%

For regular stresses I know this can be due to the interpolation, but this has no effect on the contact pressures.
Does anyone have an Idea what might be causing this and how I know which values are the correct ones?

Thanks,

Thom
