  1. Section cut in HyperMesh for check elements

    Great thank you very much! Is there also a way to cut it with the coloured element quality check?
  2. Hello everyone I have a quite complexe geometry to mesh. For this I have applied 'Check Elements Quality Index', where it shows the quality of the elements. Now I would like to know, if there is a possibility to cut the model, to be able to see the inner contours and how the elements looks there. Then I could have a better overview of the situation and know what to change for the mesh. I thank you in advance for your help!
  3. Hello I would like to know if there is a possibilty in Hypermesh to convert a surface model to a volume model? Thank you in advance for your help!
  4. Difference MINDIM, MINMEMB

    Thank you!
  5. Hello Is it possible to highlight in colour only the lattice structure? I get only one component, which contains the lattice elements as well as the full material. So they both have the same colour. I thank you in advance for your help!
  6. Difference MINDIM, MINMEMB

    Hello Is there a difference if you set MINDIM or MINMEMB? You can go either to Analysis>Optimization>Topology>Parameter and then change minmemboff to mindim with a value, which will assign it to the Design Variable Property. Or you can go to Analysis>Optimization>Opticontrol and set MINDIM with a value, which creates a new optimization control named 'optistruct_opticontrol'. Thank you in advance for your help!
  7. Lattice structure minimum diameter

    How does the MINDIM work? I have changed the elment mesh size to 7.5 mm and set MINDIM to 0.5 mm. But I still get lattice structures with smaller diameters (Ømin=0.038 mm).
  8. Lattice structure minimum diameter

    Hello Thank you! Well the minimum diameter is also related to the element size. I guess by setting a mesh with enough big elements, will create bigger lattice structures.
  9. Lattice structure minimum diameter

    Hello Normally a lattice optimization does create lattice structures of different elements. Does a way exist to set a minium diameter of the lattice structure? I know the function 'MINRAD', which cleans in the second optimization phase and eliminates all elements above the set value. If I use MINRAD, almost all lattice structures are eliminated, as they are quite small (between 0.0027 and 0.335 mm). The ideal lattice structure would have diameters above 0.5 or 1 mm. How can this be set? I thank you in advance for your help!
  10. Measure lattice diameters

    Thank you very much!!
  11. Cross section

    Perfect! Thank you very much!
  12. Measure lattice diameters

    Here are two extracts from the <filename>_lattice.fem: CBEAM 12983 6184 7674 37285 1.25373 2.25 1.75 PBEAML 2 1 ROD + .1790678 0.0 1.0.1790678 What column stands for the diameter? Thank you for your help!!
  13. Measure lattice diameters

    Hello I have made a lattice optimization. Now I would like to measure the diameter of the lattice beams. Do you know how to measure them? I thank you in advance for your help!
  14. Cross section

    Hello I have made a lattice optimization. Now I would like to make some cross section through the model. How can it be done? I thank you in advance for your help!
  15. Topology optimization with design/non design components

    Thank you in the meanwhile the problem got solved.
