Dear experts

I could not read LS Dyna input files formatted as k extensions (XXXX.k),  
though paraview allows k extension files.

Could you tell me how to read them?

Sincerely

the `LSDynaReader` does support `.k` files, but I do not see any tests for it.

Could you share your data ?

Best,

@mitm

Thankss for sharing [THUMS | Toyota Motor Corporation](https://www.toyota.co.jp/thums/), however there is many datasets there, but could not find one in the .k format. Please point to a specific dataset you want to open.

Dear Mathieu

Thank you for your kind reply, and apologize for my late mail.

There are main three models as the below,  
(1) AF05\_V7\_Occupant  
(2) AM50\_V7\_Occupant  
(3) AM95\_V7\_Occupant

I first would like to use the (1).  
But I could not read all .k format files in it.

I would appreciate it if you could help me.

Kind regards

ParaView is unable to read any of the .k files present in the files you provided sadly.

I do not have access to other .k files to try but maybe @utkarsh.ayachit knows more.
