    Logical Processor Usage

    Hi Omer Faruk GUMUS Normally it is recommended to set the number of SPMD domains (np) equal to the number of sockets and to set the number of SMP threads (nt) equal to the number of cores per socket. With a low number of cores (below 32), a pure SPMD run might be more effective but the performance gap should be small. With a very high number of cores (1024), it is possible to increase the number of SMP threads up to the number of cores per node and set only one SPMD domain per node to maximize performance if the limit of scalability of the interconnect network is reached Check this document and also refer to the Radioss parallelism topic (page 47) discussed in the e-book https://altairuniversity.com/free-ebooks-2/free-ebook-crash-analysis-with-radioss-a-study-guide/ Radioss_parellelism.docx

    warning

    Hi JIAYU SUN This is because the GeForce series of Nvidia is not officially recommended by HyperWorks. However, this warninig message only appear once. You can proceed further and you may experience some graphical issues in the future. HyperWorks_2017_Hardware_Recommendations_and_Certifications.pdf

    Installation Student Edition 2017

    Hi Laura27 When you click on this link, HyperWorks student edition package will be downloaded which has the above-mentioned features. As you mentioned those aren't separate links but is a single link for HyperWorks student edition download. When the download is finished, install the software and use the altair_lic.dat file attached with the mail. Set the license file by creating an environment variable as described in the mail.

    Error 9

    Hi Sharath v g Use windows folder options > unhide known extensions, to make sure the file is named altair_lic.dat and not altair_lic.dat.dat, You need to confirm if the Ethernet address in the license file is the correct one and matches the one in your machine. When you open the license file in a text editor you will see an Ethernet address there in a line that says "ETHERNET = The Ethernet ID is the ID of your machine which is exactly 12 hexadecimal numbers. For example D4WRF478F398 Run ipconfig/all in command window and check for physical address under Ethernet adapter local area connection: The listed physical address under Ethernet adapter local area connection or Ethernet adapter Ethernet should be used to generate the license file. That means if the address provided as above does not match the one in the license file, please request for the license file again with the correct Ethernet ID. You can check your computer’s Ethernet address, by using the almutil -hostid application from the Start > Altair > Tools > Admin tools Menu and compare it with the result in the command window, Alternatively run getmac in command window to find out available Ethernet addresses to cross check as well

    Meshing guidelines

    Hi Rahul Prakash Download the e-book practical aspect of finite element simulation which discusses different methods of meshing. You can as well get documentation/ tutorials/ model files for meshing. https://altairuniversity.com/free-ebooks-2/free-ebook-practical-aspects-of-finite-element-simulation-a-study-guide/

    Error During HM Launch

    Hi Tohid Please reconfirm that you have deleted the hmmenu .set, command. cmf , hmsettings .tcl from the working directory. Also, remove .altair folder in the users HOME directory. Reboot the machine and try invoking HyperMesh. .

    ERROR 9 Hypermesh

    Hi sara22 Check and ensure whether you have created the environment variable correctly. Move the license file to a location that does not change and give that path while setting up the environment variable.

    Invalid License Error: Compose Basic

    No, you cannot install student edition in multiple computers. It is locked to the Host-id which you used to generate the license file. If you want to use it on multiple computers and for commercial purpose, go for the full edition. See the limitations of the student edition https://altairuniversity.com/altair-student-edition-limitations/

  18. Hi forestis HyperWorks do support Nvidia graphics cards, but not the Geforce series. Nvidia Quadro series is officially recommended. The Quadro series is more geared towards CAD and graphics designs, while the GeForce line leans towards gaming. However, you can still work with the GeForce series. The thing is, you may face some graphical issues. Check the GPU recommendation of HyperWorks (pdf) Also, check this to see the difference between Geforce and Quadro series of Nvidia. You can understand which series is best suited for software/simulation/design application. https://www.quora.com/What-is-the-difference-between-Nvidia-Quadro-and-Geforce-How-each-of-them-perform-on-CAD-and-Gaming hyperworks_2018_hardware_recommendations_and_certifications (1).pdf
  19. Hi Nitin Jain The recommended element types in Radioss for spot weld creation are shell element. Surface 1 and 2 for each solid spotweld should always connect with a shell element. If one surface of one solid spotweld is not connected with a shell element, then the stiffness will not be computed correctly and an error may occur Since you are having solid elements you have to create a shell coat and then connect using spots. There are three different ways of modeling spotweld: • Node Connect • Spring (/PROP/TYPE13) Connect • Solid Connect When you create a spot weld using type 2 spring, by default you will get the (TYPE13 spring property + TYPE2 contact). In your case since you have to define max tensile strength of spot weld as 40% of the base material, then I recommend you use the solid connect method. Here you can specify separate failure criteria. This is explained in detail in the Radioss help documentation. Please have a look Also, have a look at the Radioss example on solid spot weld creation. I have shared the 2 example deck files, which is modeled using default spring contact and also solid connect. Check that too. solid connect.zip spring_beam_spotweld.zip
  20. Hi Nitin Jain I will check and update you.
  21. Hi Can you please share your model. You can use the secure drop box link https://ftin.india.altair.com:8443/filedrop/~Ma3TaE

    Hi Germanstudent Delete the settings file and try again. Restart HyperMesh and see if you get the crash.

    Elements check

    Hi Sumit Patil This video on Element quality checks may also help you. https://altairuniversity.com/learning-library/hypermesh-element-quality-check-and-mesh-styles/ Also, download the e-book "Practical aspects of finite element simulation" in which mesh quality checks are explained in detail. https://altairuniversity.com/free-ebooks-2/free-ebook-practical-aspects-of-finite-element-simulation-a-study-guide/

    Listing Loads

    Hi karth If it is labeled as 123.., then it would be a constraint rather than a load. 123 represents the degrees of freedom. This would be some conversion error. You can add loads to the required nodes after deleting those constraints.
  25. Pranav Hari

    Listing Loads

    Hi karth Did you try this? Go to Analysis panel > loads. Tick on label loads which will display the magnitude. Use the "uniform size" panel to adjust the size of the load vector.
