i work in full version not student.

could you send *.fem file?

easy)

I run with v13 => result has 'element thickness'

maybe v17 is different . anyway, view 'element density' for the same meaning

i've got the answer from support team.

Hi, Marat!

I figured it out. Before clicking “Apply” in HyperView, you need to select the component “design”.

Otherwise, the component “nondesign” has element density 1 because its thickness was not changed during optimization.

The newer version of OptiStruct is not simply replacing the term “element thickness” with “element density”, but the definition of those two are different.

“Element density” means the percentage of material variation is used, so the upper bound of this result is always 1.

In this example, “1” means 0.3mm base thickness + 100%*0.7mm variation thickness = 1mm; “0.5” means 0.3mm base thickness + 50%*0.7mm variation thickness = 0.65mm

Two pictures below show the difference of plotting the contour with “design” component selected and not. They are the same result, and they look different because the color of nondesign component.

finally, v17 can't show element thickness like v13?

altair team, please downgrade it!
