Lapis1 is on a distinguished road
I have successfully modelled, meshed, loaded and finally simulated what is to become a load cell. Unfortunately I am stuck on one specific part that regards general post production.

There are stress-relief channels on two of the four parts making up the entire load cell, with one of the volumes shown below (fig 1). I am interested in obtaining a contour plot of the von Mises stresses occurring at areas 527, 802, 803. I could easily obtain a contour plot of the von Mises stresses specifically for area 527 by moving the working plane around this area, then opting for a Q-Slice Z-buffer in the Hidden Line Options (fig 2).



(fig 1)



(fig 2)


The problem lies within the fact that the Z-buffer does not work for curved surfaces. The closest I have come to obtaining a contour plot of the curved areas was was by selecting areas; selecting associated nodes; selecting associated elements; plotting von Mises. Unfortunately this provides a jagged and unclean result as seen in (fig 3).



(fig 3)


Is it possible to get a smooth result as seen in (fig 2) while also incorporating curved areas / the channels?

Thank you in advance!

Which software are you using, CFX? You would be getting smooth surface contours at least with Fluent just by plotting a contour on the selected face. I haven't used CFD-Post for a while, but I would say that it would be possible also there.

Maybe give CFD-Post a go? Or read the case and data files into Fluent.
