  1. Hello, I'm looking for tcl code to create rigid elements connection between two sets of nodes with selectable DOF, searching tolerance and local coordinate system. I tried to find something in script exchange, but unfortunately I didn't find anything. Have you any idea where can I find something to solve this problem? Maybe is there any build-in function in HM? I know spotweld tool, but I want to write all-in-one tool. Thank you in advance
  2. "Skin" results output for solid elements

    Thanks, I prepare sets (nset for displacement and eset for corner stress) and everything works fine, but I had to edit .fem file using text editor. It is not possible to set any type of sets using HM v14 - gray window for SID.
  3. Change TIE to other connection

    Hi, Modal analysis: 5-350Hz (Abaqus solver found 4 resonance modes). Number of nodes: 5 000 000 Elements order: HEXA and QUAD first, TETRA (most elements) and TRIA second Now only one step: modal (in abaqus I set 4 loadsteps: modal and frequency response for all axis)
  4. Change TIE to other connection

    I tried to change tie to rbe2 but still I need 1TB memory for scratch (core OUT) or 0,5TB RAM for core IN When I calculated this model using Abaqus solver I need much less memory. Only solution I found is to change method from EIGRL to EIGRA (need only 13GB RAM)
  5. "Skin" results output for solid elements

    Hi, could you tell me how should I write command to output results only for membrane? For example: STRESS(,H3D,,,CORNER,,,,) = SID. What kind of set is SID?
  6. Hi! I have problem with TIE connection. I imported and converted model from Abaqus with TIE connections to Optistruct. My model is ready to solve, but I discovered that TIE connection need huge memory space (Core IN: 350GB, Core OUT 800GB , without TIE Core IN 40GB). Has anyone any idea how to replace TIE connection to other? I thing the best element for "TIE" should be RBE2. Ps. My TIE connection contain "contact surfaces" and "groups" (Card image: TIE). Ps2. I know that the simplest way is to create "spotweld" but how to use previously created "contact surfaces"?
  7. Hi! I'm calculating big models containing solid elements and I would like to reduce size of my results file by saving only values for boundary skin. I use this technique in other solver and it works fine. My question is: it is possible to set some parameter or card to do this in Optistruct? Thank you in advance
  8. Hi, Is there somebody who use Optistruct to calculate PSD/Random analysis? I know that it's possible, I know how to do that and also I prepare this in my job (I used to work in Nastran, .fem and .bdf files are almost the same). But I have another question: use somebody this solver in job for this type of analysis? How about results comparison between Optistruct vs. Nastran and Abaqus? I asked, because I heard that it is not good idea to use this solver for dynamic calculations. Have you any examples, comparisons, articles etc. focused on obtained results from this type of analysis? I prepared similar analysis in Optistruct and Abaqus (our main software for FEA), and RMS stresses are 10% lower in Optistruct (tomorrow I check both models again). I observe that Optistruct solver is much faster when I set output for all frequencies (opti 20min, abaqus 3h ), when I set output only for last frequency opti:15min, abaqus 25min. So that's why I'm asking about this Thanks in advance
  9. Hi, Is there somebody who use Optistruct to calculate PSD/Random analysis? I know that it's possible because I prepare this type of analysis in job. I know also that .fem/.bdf file is the same as in Nastran, but maybe somebody use this in job? How about results comparison between Optistruct vs. Nastran and Abaqus? I asked, because I heard that it is not good idea to use this solver for dynamic calculations. Have you any examples, comparisons, articles etc. focused on obtained results from this type of analysis? Thanks in advance EDIT: I added topic to wrong category and unfortunately I cannot delete it please delete this topic
  10. Great idea Thanks Unfortunately this script is not working when I tried to run it like regular .tcl. Probably it is working only with "legend settings" window There must be something more
  11. Thanks, but I'm looking for tcl command, because I would like to add this to my script (High resolution screenshots). I know that I can change it manually
  12. legend font colour

    WOW, why my post was deleted? EDIT: I found it in another topic. THX
  13. Hi, I have a question according this topic. I'm looking for tcl command for HyperView to change legend font size and coordinate system font size. Anyone know syntax? I need this for CaptureActiveWindow, because when I set high resolution, fonts size are too small (font size is in pixel ). Thanks in advanced
