  1. Hi, Thanks to all of you for your valuable time and efforts putting in helping others. Things are like that,i have a surfaces with many small lines.I suppress these lines to do some geometric analysis.Then i want to restore(unsuppress) these lines. But i find when i suppress a line,its line_id will change.So i don't know how to choose precise line_id to unsuppress. What I can think of is choosing all lines,then do unsuppress operation.However,it will cost extra time and take another troubles in next step. So how can i store the suppress lines and unsuppress them precisely? Thank you very much!!!
  2. Hi, Thanks to all of you for your valuable time and efforts putting in helping others. I know a command *elementtestjacobian to find the bad element.But now i desire to know preciese jacobian for any element.Then i can calculate the min,max jacobian. When i am in F10 plane and click any element ,i can see the precise jacobian.So i think hypermesh has this api interface. However,i spent a lot of time not finding it. If you know how to do this, it will save me a lot of time.I am very grateful for your help! Thank you very much!!!
  3. Thank you very much!!You help me a lot!!
  4. Thank you very much!I translate 2D mesh a bit and translate it by reverse direction.Then it breaks association!
  5. I tried it, but the problem is like that:for the same facet,only one 2D mesh can exist.Any other 2D mesh for this facet will overwrite the old one no matter which component it is in.
  6. However,i find a new problem.If i mesh same facets for twice,new mesh will overwrite the old one.But i need old one to do reference.
  7. Yes,you are right!it corresponds *deleteelementsmode to script.Thank you very much!!!
  8. Hi, Thanks to all of you for your valuable time and efforts putting in helping others. I have a solid.And i mesh some facets by 2D automesh.Then i suppress some lines in these facets to improve mesh quality. But i found when i suppress lines,the original 2D mesh will change,the mesh in facet which lines(suppressed) belongs to will disappear. However,i need original 2D mesh to do some reference.Now i use *feoutputwithdata and *feinputwithdata2 to store original mesh.But the reading and writing file takes a lot of time. Do you know another method to fix(store) 2D mesh ?I am very grateful for your help! Thank you very much!!!
  9. Hi, Thanks to all of you for your valuable time and efforts putting in helping others. I have a Hexahedron mesh.I want to find the boundary points(most external points) to do next research. I don't find functions in api,but in hypermesh it has operations(wireframe elements && wireframe elements skin only),which shows in hypermesh it can identify the boundary points. If you know how to do this, it will save me a lot of time.I am very grateful for your help! Thank you very much!!!
  10. Although the final result is not the same as I originally thought, this is enough. Thank you!
  11. yes,i tried this.i used it like: *createmark nodes 1 nodeid *findmark nodes 1 1 1 nodes 0 2 But it said that nodes are not attached to node.I think the reason for the error is that "by attached" is not acceptable for nodes.
