Can I get a “layered” stress field output through the height of my model?

    • deld

      I have a thermo-mechanical simulation with an Equivalent Stress output. I want to illustrate the concentration of stresses in the z-axis through the height of the model at a specific point in time. 

      I figure I could achieve this by manually creating several surface planes through the z-axis (e.g., each surface plane would be offset 1mm so that I have 6 planes through a 5 mm tall component) and taking screenshots of the Equivalent Stress output of each "layer". I could then use these images to effectively demonstrate how the stress changes through the height of the model at a specific point in time. 

      Is there an easier way to output this type of data, or is my manual approach likely the simplest method?

      It might be easier to interpret results obtained by mapping the stresses to a pattern of construction lines (rather than surfaces). The lines could be aligned with the z axis and extend from the bottom to the top of the 5 mm high component. The creation of either lines ar surfaces, the mapping of results onto them and the display of these results can be automated with an APDL command object, but I don't know if it would be easier for you to create such a command object than it would be to perform this post processing operation manually in the Mechanical GUI (that would depend on your comfort with/knowledge of APDL).

      Multiple paths/surfaces may be created by embedding the commands in do loops (*DO command).
