  2. 非線形解析における途中結果の出力について上記記事がありますが、 PARAM,EXPERTNL,NO や NLADAPTのDIRECT=YES を用いると自動増分調整機能がオフになるため、収束せずに計算が終了しやすくなることがあります。 自動増分機能が有効な状態(初期設定)で任意の荷重増分・時間増分での結果出力を行う機能があります。 NLOUTのTIMEオプションです。 NLOUT, id, TIME, setid SET, setid, TIME, LIST, 希望出力時間を並べる となります。 例えば、 NLOUT, 999, TIME, 888 SET, 888, TIME, LIST +, 0.2222, 0.444, 0.666, 0.888 としますと計算時に必ずそこを通過し、まさに指定したタイミングでの結果が得られます(最初と最後は自動的に出力されます)。 本機能は、OptiStruct2019.2でご使用頂けます。 EX2shell_largedisp.fem

  6. MultiScale Designer 2019.2 がリリースされてます。 ところが前述の例題のうち OptiStruct と Radioss のプラグインを使う節で、計算がうまく流れません。 例題付属の mdsFiberOri.dat を mdsFiberOri.dat に差し替えて使ってください。 射出成型解析のところで全ての配向テンソル成分が 0.0 になってるところがいくつかあるのが原因です。MultiScale Designer は 2019.2 で精度と速度の改善がされていて、その影響で、おかしなデータだと(ちゃんと)おかしな計算になるようになりました。 例題も回避すべく鋭意更新中です。
  7. Good Afternoon, I am trying to export mesh from Hyperworks 2019X CFD. However I have reason to believe that my install was corrupted. Attached are some pictures of my UI to show you what I have displayed. To start with, I am not able to view the components in CFD as I would in structural 2019X. I am not able to hide the components in order to view the mesh only. There are no options to export the mesh from the left side menu. There is no button based UI on the bottom of the screen as present in the optistruct version of the software. There is no ribbon at the top of the screen that allows for export. Please let me know if there is something with my install. If possible would anyone know how to re-complete the install/ fix the install?
  8. Hi, In the pictures shown, I am using the mesh refinement toolbox as instructed by the guide, however instead of a refined mesh, it is also shrinking my elements: Result: Can anyone explain? Thanks Edit: With a more refined mesh:
  9. Good Afternoon, I am very new to hyperworks and have recently installed the newest Hyperworks 2019X. I have noticed that there is very little documentation for the new UI of Hyperworks. I understand that it is still in development, but this has been problematic for a number of reasons. I am trying to use the virtual wind tunnel for speeding up some basic fluid analysis tasks in my workflow. However I seem to be getting an error that says that I can not complete the analysis on a windows computer. The specific error that I get is, "Local runs are not available on this platform". When I look at the documentation provided with the software, I see that in the analysis step, "If you are running VWT on a Linux system with a supported GPU, no further configuration steps are necessary. If you are running VWT on a Windows system, you'll need to have a Linux installation of ultraFluidX available for running the solver. To run the solver from Windows: Click Export. Copy the .stl and .xml files that are created in the run directory over to Linux. Launch the solver by executing the ufxRun script, located in the installation directory at .altair/hwx/bin/linux64/ufx/scripts. Use the ufxRun -h option to view the help page." OK so I need a linux computer, which is very difficult to obtain for me. Also I read on some old forum posts that Ubuntu is not a supported linux version for Hyperworks. Also when I use the download tool on Altair connect there are no options for a linux install of Virtual Wind Tunnel. How am I supposed to use this tool if there is no documentation for how to even get it to run on a standard windows machine, or an install file for a linux machine?
  10. Hi. Try /PROP/TYPE51.
  11. I am new to flux environment and I have been modelling simple EM use cases. One such use case is H field calculation for a single conductor carrying current in air medium. I drew and plotted the magnetic field magnitude (A/m) using the sensor functionality. I am however finding it hard to compare the result with hand calculations. The expression for H is Current/(2Xpi X distance). The simulation result does not seem to match with the hand calculation. I see the result is off by the order of 10^6. I suspect, I may be reading the units erroneously. Please lend any help in understanding the output units of flux simulations.
  12. If you have no rail curves or edges, the constraint box is editable after selecting your profiles. Select profile edges or curves Right click Edit the constraint / continuity type in the control panel At this time the focus is lost from the guide bar since you clicked inside the control panel. Click the green check mark to complete the Loft. If you find that the constraint option is locked, it is because no profiles or rails are currently selected in the edit mode.
  13. You may be able to accomplish this using FVX scripting. You can get FVX information in the /fv/help/FV_ReferenceManual.pdf included in the installation. The attachment has an example from which to start, then maybe use the 'modify' command within a loop to change locations and perform the queries. (You may want to consult with your local Support team as well...) test.fvx
  14. Supported Ls-Dyna result types: HyperView LS-DYNA Results Reader.pdf
  15. The first thing to try is to copy the examples to a location where you are certain that there will be no problems with write permissions. (Maybe you had already done that).

    By default the power superposition is considered in ProMan for the superposition of the individual rays (representing the mean signal level), but also the coherent suerposition (considering the phases) can be activated, which then represents the fast fading (probably the pattern you are expecting). Similar process can be applied for the superposition of the results from two transmitters: Either the power values of the two transmitters can be added, which represents then the expected mean signal level considering both transmitters Or the phases for the superposition can be considered, which would assume that both transmitting antennas are synchronized. In this case the rays from both transmitters can be superposed based on the fieldstrength and phase values given in the .str files (one .str file per transmitter). The .str files can be also generated using the WinProp API.
  17. Hi, using 2019.2 and defining the time instance in the attribute TimeInstance of the class WinProp_Additional we are getting different results for different time instances, i.e. when loading the results in ProMan GUI, both the object and the related shadowing area is moving. Please find attached a corresponding ProMan GUI project with a simple moving box, where the same results can be achieved by using the WinProp API. I was adaping the APIExampleCPPIndoorPropagation and setting the time instance to 0s and 1s. TestSimpleMovingBox_2019-12-09_09-38.zip
  18. Hi mate ! You can use for example TIE constrain to link the master surface with the slave one. Normally, in contact problem we refine the mesh of the slave surface. But I think in your case, linear static analysis, there will be not so much difference. You can use the automatic mesher and mesh the parts using Tetra approximation. It's okay if you use Tetra finite element ... But in Nonlinear static analysis, we recommend to refine contact interfaces (slave surface) with S2S discretization to ensure the convergence of the contact pressure. You welcome mate
  19. Hi Farouk, I unfortunately didn't understand it so well. Can you please explain it to me? As you can see from the picture above, I have 3 parts and I want to make a glue contact between the parts. For the glue, I made a solid component to define the material information (the gray part is the glue). (except the yellow part, the other two are solid) How should I mesh the parts? Does my mesh have to be identical on top of each other? (2d, 3d) Can I only mesh the contact surfaces identically (quad / hexa) and mesh, the rest of the solid part(where no contact arises) Tetra? I need some help/tips to finish my thesis. Thank you in advance! Best regards
  20. Hi Bhanu, Check the CONTROL CARD in OptiStruct "OUTPUT" where you can control the files you want to be written. Kindly find attached the link from help document for the same: https://altairhyperworks.com/hwhelp/Altair/2019/help/os/topics/solvers/os/output_io_r.htm?zoom_highlightsub=OUTPUT Thank you
  21. Hi all, I am using the WinProp API. When I output the Rays.str file in a SRT simulation I cannot get the transmission matrix values as provided by the GUI. Could anyone tell me if I am missing any parameter in the API? This is what I get with the GUI: This is what I get with the API: I would like to have the transmission matrix values as well.
  22. Hi, You are right, following the steps in the pdf file, when I load the macro I get the same error message as you. To avoid this error messgae, once the goemetry is created you need to unload the Overlay. To do it : • Leave the context Overlay once the goemetry is created • Go in the extensions >> select Use overlay >> right click >> select unload Once the overlay is unload, you load the macro and run it. With this modification it work well. Best regards.
  23. I am using LSDYNA as solver and then hyperview as postprocessor. Any idea how to extract beam stresses from LSDyna result files?
  24. I didnt find HW_USE_OPENCL to set it has environment variable.So, i created it in user variales gave path by browsing file and selecting desktop shortcut of hyperworks application, but still error remains
  25. Hi, In the 2019 version we made changes in the graphic engine. Please test briefly if the environment variable HW_USE_OPENCL changes the behavior. Please do the following steps: 1. Stop all instances of HyperWorks 2. Set the environment variable to HW_USE_OPENCL=0 3. Start HyperWorks and check if the behavior has changed when clicking Grids. or Try updating graphic driver.
