  1. Hi FABIOMUSICCO Upgrading your graphics card will solve this issue. Here are the recommended GPU's for HyperWorks HyperWorks_2017_Hardware_Recommendations_and_Certifications.pdf
  2. Hi Check this HyperWorks_2018_Installation_Guide.pdf Server-installation.docx
  3. Hi VAL1 Have a check whether this forum post can help you.
  4. Hi gopal_rathore According to the e-book "Dynamic Analysis with OptiStruct" there are no such thumb rules. The natural frequencies and normal modes of a structure can be a function of the load and the damping present on the system. A system with N DOFs will have N natural frequencies. Have a look at the e-book (page 77) modal transient analysis is described in detail with a tutorial. https://altairuniversity.com/free-ebook-learn-dynamic-analysis-with-altair-optistruct/
  5. Hi Sritej Kalas While creating the loadstep, change the analysis type to complex eigen. I also recommend you to upgrade your version of OptiStruct Have a look at these 2 tutorials from OptiStruct help which is similar to your case.
  6. Hi Julio Also, try geometry > surface edit > extend. Select all the surface and click on extend
  7. Hi harshitpuri I recommend you to update to the latest version of HyperMesh and try again
  8. Hi harshitpuri Have you checked this example file from Radioss help? In this example, type 16 & 17 interfaces are used. gears.zip
  9. Hi Cnaaaaa The student edition is not meant for commercial use. The license file for student edition which you receive through the mail is locked to the host-id of your Laptop/Desktop which you have used to generate the Host-id. If your university has purchased the full version license, then you can install it on your lab. Have a look at the Installation guide and also check and ensure the connectivity between the servers.

  10. Hi WRCpce2018 If you want to re-analysis the optimized shape, you can use the OSSMOOTH option from Post > OSSmooth. After you have completed your run, you will get the .sh file from your run directory. The .sh file has the attributes of the new shape.
  11. Hi cemreyvz Can you please send a screenshot of your error or the model
  12. Hi Cnaaaaa Can you please confirm which version are you trying to install? The student edition in your laptop or the full version in your lab. The method of installation for both these are different.
  13. Hi Sumit Patil Can you please explain more about the error
  14. Hi Beginner93 You can do a quality check in Hypermesh to see whether your mesh has passed it. Tools > Check elems Have a look at the e-book "Practical aspects of finite element simulation'" (https://altairuniversity.com/free-ebooks-2/free-ebook-practical-aspects-of-finite-element-simulation-a-study-guide/) Refer page 309 where element quality checks are explained in detail
  15. Hi Madhura 1. Right click on the model browser and click create a curve. 2. click "new" and create a new curve. Change the option to /Table/1 . 3. Close all other windows and select the curve you just created from the model browser. change the options as in the image below. click on data:Ifunc and enter the values in the popup dialogue box 4. There will be 3 fields to define. Ifunc, Strain rate (Ai) and Temp (Bi). HM lists this as Ifunc, V(0), V(1). 5. Now you can assign this curve from the material data: Table_ID Hope it is clear...
  16. Hi mabefa Doing an equivalence is the best option or you can manually replace the nodes through 1D > Replace
  17. Hi Cnaaaaa The error is because you are not able to connect with the license server. Check and ensure that you have connectivity between the servers. Try to ping the server and check whether file sharing works both ways between all the machines. Also add an exception to the port 6200 in the firewall - in the server and the client machines.
  18. Hi Cnaaaaa Unfortunately, this is currently not possible in OptiStruct or Radioss. Composites are not supported in transient heat transfer. it is planned for the version of HW 2019.
  19. Hi volkanyildirim48 Once the STL file has been imported you can then use Geom > surfaces from FE and select the highest complexity in this panel > select the elements to create surfaces from STL, hence you can create geometry from stl. To directly solid mesh your STL you can use ShrinkWrap also You can achieve a good tetramesh for all purposes, using the Shrink Wrap panel. The shrink wrap can generally be used as a quick mechanism to generate solid meshes. 1. Go to 2D > Shrink Wrap panel. 2. Here there is an option generate solid mesh – this will produce an all-hexa or all-tetra mesh based on the selected elements or geometry. 3. Make sure the generate solid mesh checkbox is active 4. This will expose a tet collapse input, please try several input values depending on your quality requirements. Check this forum post too..
  20. Hi michel Can you try this in Radioss? Defining such contacts and interface is easier in Radioss. You can also refer the tutorial RD-T 3595 from Radioss help, which is similar to your case
  21. Hi rrishav This TCL gives you the output for Material Name, Card Image, E, Nu, Rho, G. I think you can modify this as per your requirement. GetMatProperties.tcl
  22. Hi VAL1 It is possible if you use an orthotropic material card. According to online help MAT 3 has the capability to apply youngs modulus in different directions. Have a check at the different card capabilities from the online help
  23. Hi RKHOMES Try relaunching HyperMesh after deleting the settings file.
  24. Hi sclifford The Regional account manager will contact you soon.
