      Hello

      I installed the latest version of ls dyna. But for mat_197, which was changed in the 2021 update, unfortunately, this update is not included in ls prepost. How long will this update be considered?

      Hello Amir,

      Please install the latest LS-PrePost V4.9.8-08Sep2022. The LS-PrePost that comes with the Ansys installation is not the latest one.

      https://ftp.lstc.com/anonymous/outgoing/lsprepost/4.9/

      With the latest version, you should be able to have access to *MAT197:

      Hi Reno. For the latest version you say. IType=5 in it?

      If Itype=5, FYRIM and DFRIM parameters will appear

      Hello Amir,

       

      ITYPE=5 is still not available in the latest LSPP. Please use  a text editor to edit this option for now.

      Hello Reno. How can I send a message to the editor?

      Hello Amir,

       

      Open the model (.k file) with a text  editor (Notepad, PSPad, etc.) and modify the *MAT_197 keyword; set  ITYPE=5 and add  the FYRIM and DFRIM options.

      Hello Reno

      Thank you very much for your guidance. Can you just send an example of editing? Where should I add?

      Hello Amir,

       

      I cannot send files via the forum. Give it a try and let me know how it goes. Please  consult  the LS-DYNA user manual for  the  keyword  format:

      Hello Amir,

      In the manual, you can see that the FYRIM and DFRIM parameters are on card 8:

       

      Your *MAT_197 keyword should  look like:

      Hello Reno. thanks a lot . So I have to add fyrim and dyrim according to the picture. And enter the desired parameters under it?

    • Reno Genest

      Yes. Also, card 4 will have to be modified according the the manual when ITYPE=5. Please check the manual, because I may have  overlooked some details. All you need to know is in the user manual.

      The Sep16 2022 version is now available. Download it and it should have ITYPE=5 in it. If not, please wait  for the next  release.

      Helo Reno 

      Is this version of ls prepost compatible with ls Dyna R13? Can I run in it?

    • Reno Genest
      Ansys Employee

       

      Yes. You will have to download the LS-DYNA R13 solver:

      https://lstc.com/downloader/page.html

      username: user

      password: computer

      If you go File > Run LS-DYNA in LS-PrePost, it will take you to LS-RUN:

       

       

      You can run your LS-DYNA model (.k file) using LS-RUN. Here is a video tutorial:
