  5. you were asked to provide further information by email, please check all your email folders (spam etc) and then write to edu-support@india.altair.com for anothe rcopy of the email, thanks.
  6. Some more relevant information http://www.altairuniversity.com/learning-hyperworks/nafems/
  7. Could you tell us the operating system and other machine specifications like the graphics card etc. (enter dxdiag in start > run and send us a snapshot of the display tab) If you are using windows 10 the software is not supported, also check about the graphics card as in the below post.
  8. Check out some new feature videos in SimLab here http://www.altairuniversity.com/learning-library/?type=learninglibraryitem&search=simlab&filter_resource_type=&filter_discipline=&filter_language=&filter_source=
  9. Make sure the minimum thickness is at least 13.5 mm or more, The model must contain valid loads or be properly supported so that it can't translate or rotate in any direction, please reexamine the supports and their degrees of freedom,
  10. We provide the tutorial model files for student edition users here http://www.altairuniversity.com/learning-library/model-files-for-student-edition-users-accompaniment-to-the-tutorials-in-help-5/
  11. It uses the optistruct solver
  12. I dont see this to be possible right now, will update you when this capability is introduced
  13. The visualization of run time is being constantly enhanced and we will raise a RFE (request for enhancement) for this anyway with the developers, at the moment I would suggest you look at the run directory (go to preferences > run options > run history path) and see the progress file or the .out file to understand the status of the run more accurately,
  14. The speed / accuracy settings in the run optimization window does just that, choose "faster" instead of "more accurate" You can also increase the element size, this is a sure way to decrease run time, The next thing you can do is in relation to the thickness constraints, Optimization run times increase as the thickness constraints become smaller. So to keep your run times reasonable, your geometry should not have very fine details. It should be as coarse as you can make it while still maintaining structurally significant features. Number of CPUs, make sure you use more than one CPU at least in the preferences section, the number of CPUs used during optimization or analysis runs. For larger models, significant time savings can be achieved by using at least two CPUs to perform the calculation.
  15. It is always important to specify the design space % before the optimization run, what we specify with the topology slider after the run is not a design space target, it is to analyse the quality of your results and is used as a basis to decide what is your design targets, as help says - Use the Topology slider on the Shape Explorer to analyze the quality of your results. If the topology of your shape doesn’t change much when you move the slider, this means you’ve arrived at a good solution and may even be able to make your design targets a bit more aggressive. If the topology changes significantly when you move the slider, you should consider relaxing your design targets and rerunning optimization until the topology remains consistent when the slider is moved. The optimal result is the point on the slider at which all of the load and support locations are just connected. When your optimization objective is to maximize stiffness, the optimal shape is generally found near the center of the slider marked by the star. When your optimization objective is to minimize mass, the optimal shape is often found to the far right of the slider.
  16. Hansol, Yes, in case your university has purchased HyeprWorks licenses.
  17. From Direct mail to support Does FEKO LITE not let you change to metallic material properties? I have added metallic materials to my media, but it wont let me change my object to anything other than PEC, a dielectric, or free space. For example, shown below I have a dielectric "vaseline" and a metallic "NiZn" but when I right-click on region 1 I can only change it to the dielectric
  18. I am trying to optimise a solid block for forces acting vertically on the surface and two of the sides fixed. I ran a similar analysis on abacus, and got the expected result. In Hyperworks am getting a weird analysis resulting in weird topology optimal structure. I want to perform a topology optimisation on the block and find the optimal final structure. I am using HW 14 edition for my analysis. I need someone with expertise to check the loading, BC and let me know the mistake. Attached is the HyperWorks file. and the force loadings
  19. At the moment the constraints are purely mechanical.
  20. Hi Florent, We would advice you to use the maximum possible volume or space, this is the best approach before topology optimization.
  21. Hi Jukka, The imported stl should be used as a template / guide to create solid geometry within Inspire, no operations can be performed on the STL
  22. The contact tool is now moved to the contact browser.
  23. From email to support I am using a student version of FEKO, and I have a problem while trying to export the impedance matrix from FEKO into MATLAB. I get an error saying that the .mat file might be corrupted . I would be very grateful if you could help me in this issue.
