  1. i know that possibility, but question was different...
  2. Hi When I use face tool for solid elements, face elements always has normal in direction inside solid. Is it possible to set in some options that face elements which tool-face generates has normal vector outside volume? Jakub
  3. Hi, I want to create response. It should be stress vonMises. For each response I need to pick element by id. Is it possible to make global response with all elements value, instead of creating lots of separate responses? How to do it? As some kind of vector? Results I have h3d from optistruct which hyperstudy created after model testing.
  4. all surfaces and elements are on 1 component. I want to hide surfaces with elements, surfaces without elements I want to keep. That is my issue.
  5. Hi, is it possible to select surface which has elements/nodes associate with them? I want to see only surfaces without meshing, any ideas how to do it? Jakub
  6. Hello I made shape optimization in Optistruct, Shape 1 is undercut at one level, shape 2 is undercut higher. I want to check optimum high from stresses perspective. In optistruct gradient method MFD its working. I wanted to use GA algorithm in hyperstudy to check difference. I defined model, resource as hm file, solver input as fem file. Solver optistruct. Now, I input variables, there are that two shapes. Should i pick them both? What about response? Should i find h3d which hyperstudy made and define element number and it stresses? can i pick global stresses? I am not sure how hyperstudy will change high of that cutout, how to define that to have min stress in results. Jakub
  7. i checked that I have duplicated elements with different elements set - I need that, and than tcl macro overwrite one of them unfortunately
  8. thank You, but i have some issue, when I want to pick all sets, some of them becomes empty, when I use it one by one that issue not happening
  9. Hi, I am able to create collector with name like set of elements name, which includes that element from that specify set. Could You help me to automatize that process. I have lots of entity sets and it would be great to run some tcl macro which will do job for me. I tried to looked up in command.tcl but when i use organize function it shows elements number for each elements set - that I cant use for tcl macro. Best regards Jakub
  10. Hi I try topology optimization, and its working. I wanted to check difference in algorithms, but when i want to use f.ex. SQP, message appears: *** ERROR # 1870 *** Topology and free-sizing optimization are not available when the MFD, SQP or BIGOPT optimization methods are selected on the DOPTPRM OPTMETH card. The DUAL optimizer must be used. It is weird, because MFD or SQP can (theoretically) be use for topology optimization. Maybe there are different parameters to change? Best regards Jakub
  11. Hi, I would like to optimize cross section of cantilever beam. I have beam L=100, cross section is square h and b (1<b<10 and 1<h<20), and in the end we have 2 forces Y and X direction. How can i run it in optistruct? I wanted by size optimization, but if I mesh it by shell i can optimize only one direction (one thickness). If i build solid beam how to do it? By shape optimization? I want t keep the same shape but change b and h to find solution. I have also allowable value of tip displ and yield strengh max value. regards Jakub
  12. that is exactly what I wrote. In hm14 there is no midsurf thickness option i utility - geom/mesh....
  13. Hi i build midsurf with different geometry thicknesses. How I Can automatically make property for thickness? I use HM 14 where there is now Midsurf thickness in utility - geom/mesh.
  14. I want to subtract displacement for one load case from other and see displacement plot in cylindrical system (see radial displacement). results is ony scalar value from cartesian or magnitude, cant use cylindrical system.
  15. Hi. Is it possible to create label with displacement - displacement (from other loadstep) but resolved in user system (cylindrical)??? I can see radial displacement from each loadstep (resolved in user system), but I can't subtract it between loadsteps (see difference in radial displ - only in global axis or mag). Jakub
  16. Hi all. I have quite big question. I have Post Processing Toolkit list in hyperview and i would like to add 3 buttons there. First for example with title "EQV Stress - similar to Ansys - structural" - i want it to open Contour panel with Results type: Stress Von mises + use corner data + averaging method advance Second with title "EQV Stress - similar to Ansys harmonic" - i want it to open Contour panel with Results type: Stress Von mises + use corner data + averaging method Max - Third - "Total Mechanical Strain" - i want it to build in contoru panel Total Mechanical Strain (Elastic Strain + Plastic Strain) Von mises+ use corner data + averaging method advance I dont know how much work would take building such tcl file, but if anyoune could help, I would be very grateful.
  17. Hi, I have model from ansys classic, works on, when I make cdb file to edit it in hypermesh all is ok. I import file from cdb, to hypermesh, and when i want to export it to second cdb file the message appears that there are vaild elements (only contact elements), do i want to save them. After that when I import file to ansys it doesnt work. In component table all element type seems to be correct. Do you know how to fix it?
  18. Yes, That is working in rotate and zoom of object, but I cant change frequency on two window by one click, i need to pick active window, and than change step (or substep - frequency)
  19. I mean that case, that we can plot f.ex node Position in hypergraph (from hyperview), i want to ask, if it is possible to import curve to hypergraph and than make visualization on model that point movement (X,Y,Z axis)?
  20. Hi, I have few modal analysis and I need to compare modal frequency. Is it possible to change step (or substep) in few windows by one click? For example for the next modal shape, one click and I would like to have next Hz for all windows at once.
  21. Hi, is it possible to see in HyperView some marker (node maybe) changing position in time which comes from curve (f. ex. imported to hypegraph - postition vs ange - harmonic analysis)?
  22. Can I use modal and transient animation mode on two windows (one next to another one) in that case? Can I put some markers (on node f.ex) in HyperView? - but without use measure panel?
  23. No, it is "image planes" good you asked, so i have second question, what about two windows? ;-) can i mix animation modes?
  24. Hi, i have avi file from test and simulation results (harmonic), i wanted to put avi and simulation on each other and play animation. I have problem because avi is working as "transient animation mode" and simulation is harmonic so it is working in modal animation mode. Do you know how i can set it to run avi and simulation results together? When i set modal animation mode i see only moving simulation, when i see transient animation mode i moving only avi file...
