  1. I've figured out the problem. When I export the FEM file from Hypermesh, a bunch of XML code gets dumped at the bottom of the file. OSSmooth doesn't like it. Deleting that part of the file fixes the problem, but I don't know why it shows up. If I run Optistruct from Hypermesh, that doesn't happen. See the attached file for the XML dump. Any ideas on why this is happening? carm_OPT.fem
  2. Adriano, I appreciate your help. I tried your attached model and it worked fine. I also re-ran it through optistruct and that worked fine as well. So it appears to be an issue with my simulation file. I have run the optimization multiple times with the same result. Unfortunately I'm unable to share it directly. If it helps, here is the command file tcl excerpt when I try it on my file: *createstringarray 2 "isosurf: 3 3 0.3 0 -1 0 0 10 30 1 0" "other_params: 1 0 0 0 10 0" *ossmooth_12 0 1 0 1 "E:/Altair/Temp/test.fem" "E:/Altair/Temp/test.sh" "" 1 0 1 2 The only clues are the error that is shown in HM, "BOM comments unsupported in the command", and a ossmooth.err file that contains the text "Invalid input model." Thanks, Jacob
  3. Hello, I'm running into the following error when running OSSmooth (iso surface FEA reanalysis) in HyperMesh/Hyperworks 2020 on topology optimization results from Optistruct 2020: "BOM comments unsupported in the command." Nothing is imported into the model when this message is shown. This only appears to happen when using 2020 HyperMesh and Optistruct, but if one or both are the 2019 version, it works fine. I'm also able to open up the results file in Hyperview without a problem. Has anyone seen a similar issue with a workaround or solution? Ideally, I would like to be able to uninstall the old versions of the software. Thanks, Jacob
  4. I figured it out for whoever else has the same question. I did not have the "batch" checkboxes marked in the hyperstudy "evaluate" page (evaluation tasks tab). Certainly makes sense now, but I don't think it is explained in the documentation.
  5. Hello. I am trying to run hyperstudy from batch mode with hstbatch. There appears to be limited documentation for this, but when I run from command line "..\\hstbatch.exe -studyfile [file.hstudy]", the study does not run correctly. The output says it is executing the approach, then immediately finishes and closes out of hyperstudy. Is there any additional documentation (other than "invoke hyperstudy" page in help doc) or examples on how to properly set this up? How can I tell hstbatch which study (e.g. opt1, opt2, doe 1, etc.) to run in the file? Are there additional commands required to actually execute the study? Thanks.
  6. Fady, I have had this issue before. I can usually fix it by deselecting and reselecting the check boxes under "define models". That is, DOE1 -> Definition -> Define Models. This will also make all the input variables as active, so if any of them were inactive, you will have to uncheck those boxes again. Hope this helps.
  7. Hello, I am interested in setting up a linked multi-model run in hyperstudy, where the response of the first model could violate a constraint and thus signify no need to run the second model. Is there a way to do this? If I were to wrap my second model solver execution (e.g. radioss) in a templex or compose script, is there a way to access the variables within hyperstudy (i.e. output response from first model)? This would allow me to apply logic on whether to run the second model. Thanks, Jacob
  8. Roberta, Yes this works, thanks for your help!! -Jacob
  9. Does anyone know how to register a compose function for use in Hyperstudy? My understanding is to use the preference file, however, I do not know the proper keyword. I suspect it is *RegisterOMLFunction, but i get an error saying "Unable to load OML bridge (can't find HWX binary directory)". I am able to register Hypermath functions without a problem. Thanks, Jacob
  10. Ivan, Okay I will try something similar, appreciate your help.
  11. Ivan, Thanks for trying it out. Can you think of any alternative methods to acquire the same information? Do you think this is a bug, or a feature that doesn't exist?
  12. Hello, I am interested in extracting the angular momentum of a p14_solid part after a RADIOSS impact. When I create output block, I am able to request XXMOM, YYMOM, and ZZMOM. The results in the time history file are all zero however. In fact, I am unable to retrieve anything but zeros for the following outputs: XXMOM YYMOM ZZMOM XCG YCG ZCG IXX IYY IZZ IXY IYZ IZX RKE There is clear movement and rotation. I am able to retrieve linear momentum and mass. Additionally, I have a separate part that is p1_shell, which I am able to extract all of the above parameters. Are these requests not allowed for solid parts, or is there some other piece I am missing? Thanks for your help.
