1D-Plot the Deformation of a Line / Edge

Please login with a confirmed email address before reporting spam

Hi again,

I wanna plot the deformation (shape) of an outer edge / line of a 3D-structure before and after applying an external load. The undeformed shape I obtain via a 1D-plot using the expression z over x or the arc-length out of an edge 3d node under results. The displacement I obtain via a 3D-cut line. But how can I obtain the position z over the length x in the deformed state? I´m only able to get the undeformed state. But the information about these coordinates must be available in the results, since the 3D-Plot shows the deformation. Maybe one can use the mesh nodes along that line/edge? Pls give me a hint, I´m dealing with that topic for 4 days now.

Thanks,

BR Sven

Did you try a line plot along this edge and plot the deformation w or w+z along the line?

Hello Edgar,

thanks for the fast reply. Yes I used a line plot in a 1d-plot group to plot the displacement w, which works so far. But I have to mention, that the outer edge is not a straight line but it is curved (crowned). So in fact I need to plot the position of a curved outer edge/line in pristine and deformed state.

Hi Edgar,

let me summarize:

at:

Edge-3D & Study1:

  • at z+w(x or arc length), Error caused by w (see picture attached)
  • at z, pristine outer edge contour (crowning) is plotted --> correct values

Cut Line 3D:

  • at w, displacement of the cut line --> plausible
  • at z, pristine position of cut line --> plausible
  • at w+z, --> correct calculation

Sure, from that results it would be possible to calculate the resulting real contour, howsoever.

But why do I always get pristine values for z, for all data sets? How can I obtain deformed position values?

Thanks, Sven
