  Hello, you can use LSPP SCL feature to extract results from ls-dyna databases. Please see the description and examples available here (https://ftp.lstc.com/anonymous/outgoing/lsprepost/SCLexamples/).
  
  PyDPF is another option: LS-Dyna examples — PyDPF-Core

  Hi,
  When using the DPF Server from an Ansys installation, you have already agreed to the licensing terms when installing Ansys.
  When using a standalone DPF Server, you must accept the DPF Preview License Agreement by following the indications below. Starting a DPF Server without agreeing to the DPF Preview License Agreement creates an exception.
  Please check this page for more information Licensing — PyDPF-Core
  Cheers, Ram
