How do LSPP to plot In-plane strain?

      Dear Sir

      I want to get In-plane strain in LSPP and I find a website that described how to get In-plane.

      https://www.dynasupport.com/howtos/element/shell-strain

      I couldn't find the function of "History > Element > Lower surface principal strain" so I couldn't get the In-plane strain with a plot.

      I have tried to use "History > Scalar" but it only can select elements one by one, so it would spend a lot of time to select elements.

      Could you please tell me If any solution can show "History > Element > Lower surface principal strain" or use can select elements tools in "History > Scalar"?

      Thanks!

      Hello,

      Try setting STRFLG=1 on *DATABASE_EXTENT_BINARY to activate the strain output in d3plot. Then use History > Element to plot the strain histories in LSPP.

      Dear AK

      Thanks for your reply.
      LSPP History->Element doesn't contain "In-plane strain", in-plane strain is different with prin-strain and effective strain.
      The article(below link) shows using "History > Element > Lower surface principal strain" can plot In-plane strain, but I can't find it in LSPP 4.9.

      Have any function can plot In-plane strain in LSPP?

      Hello,

      You can fringe plot as follows:

      Hi Reno

      Thanks for your reply.
      I could fringe plot as your way, I want to know detail strain result so I need to plot 2D-diagram.
      how to LSPP plot 2D in-plane-strain Dialog for many elements?
      I have tried History->Scalar but it couldn't select elements with GUI.
