      Dear Users Our Commercial and Academic users around the world can use these same forums here as before i.e. the Altair Support Forum , Commercial users from India with solver queries can go to the Solver Forum for India Commercial Users , Academic Users from India and AOC India Participants are requested to go to the Forum for India Academic Users and AOC India Participants , We will be tending to all queries in all the forums promptly as before, thank you for your understanding.

  1. Thank you for your answer, could you give me a screenshot of that tab ? I don't see the keep connectivity, also when choosing edges , it says that the biggest displacement was 0.03 , does it mean the mesh is connected ?
  2. Smooth mesh error in Solid

    Hi All Using the smooth option for a solid mesh ,I got a message like : largest displacement to final iteration :0.03, what does it mean? and why does the color of part of the mesh change to more dark? also when trying to choose a limited number of elements, it can only choose the surfaces and gives error that " no solid was selected"
  3. Thank you very much, But one question remains : How do I make sure, that after meshing, the mesh in the comon surfaces is connected? I see that sometimes Hypermesh applies slightly different mesh or nodes on two identical edge, or surfaces
  4. Hi All I know that in shell structures, when we have the midsurface, we verify that there are no free edges, what about two solid bodies, specially if I have had to trim the solid, since a part is revolutio and the other part is an extrusion, so they might need different meshing techniques ? how can I assure the mesh in continuous ?
  5. I have hide the other pipe ( with a lower diameter than this one) that intersects with this pipe on the inner circle as a shell. the ring that I have checked should be created, but the inner circle that I have crossed shouldn't be. Hypermesh creates it only cause there are those two nodes that create that arbitrary line among them and cause the inner circular curface also create. What I want is only the ring between the two pipes, like you see in the second image
  6. Hi All Sometimes I see nodes on the edge of a pipe, made of surface, that are not connected to any edge, but they create problem if you need to create a surface between the pipe and another one ,and make that surface distorted. also it can't be deleted using point edit > suppress
  7. Hi all I have a Solid ( the exhaust manifold) cylinder, where it seems like to be only shells but when I go to features like delete feature, it can be chosen as Solid. the adjacent pipes connected to this cylinder are already surfaces so I could extract the midsurface. how can I convert this middle solid cylinder to surface?
  8. Import results from Abaqus to Hyperworks

    I don't mean for hyperview, I meant to apply other load cases , like electromagnetic analysis etc
  9. Hi All Is it possible to import Abaqus ODB results in Hyperworks, to continue solving the problem if Abaqus has not that solver for example?
  10. Hi all what is the meaning of the number in tetcollpase blank which is by default set to 0.3 ?
  11. Hi All how should I choose the external surface of a spherical shape as a surface , when I also have meshed it ? I tried elements but the problem was that I could not use any option to select all the elements on the external surface, options like adjacent ,etc don't work
  12. Topology optimization error

    Thank you very much. How do I reach this menu ?
  13. Topology optimization error

    Thank you very much. Is there any article that I can read about compliance and weighted compliance ? also , why is the contact definition in optistruct so generalistic ? without allowing me to choose the contact surfaces? CONTACT 1 0.3 NORM
  14. Topology optimization error

    what do you mean by load weight ? also , does compliance that I see in theory differ from weighted compliance? So you mean to remove the Volfrac variable?
  15. Topology optimization error

    It is one load case, static, applied to nodes on a line.what was not clear for me was the error text, what does subcase mean ? I don't have the access to file to share it now
