To be able to define a senseful result extraction from such binary files you must know what is stored in those files. Unfortunately, you cannot see the file content within that LS-Extractor dialog. Please have a look at the LS-DYNA help for Keywords *DATABASE_ and *DATABASE_BINARY to learn more about binary output files and possible content. Or use LS-PREPOST to control the content of the binary files. Please note, the LS-DYNA-Output-node (or LS-Extractor) cannot be used to read TXT or ASCII files.&lt;\/span&gt;&lt;\/p&gt;&lt;p class=&#8221;MsoNormal&#8221;&gt;&lt;span lang=&#8221;EN-US&#8221; style=&#8221;mso-ansi-language: EN-US;&#8221;&gt;The LS-DYNA-Output-node (or LS-Extractor) is automatically added when using the Solver Wizard to enable a response extraction without the need to integrate a LS-PREPOST or any other postprocessing tool. But if you like you can replace the LS-DYNA-Output-node with a batch node (eg. to start LS-PREPOST with a command file writing specific results to TXT files as you described) followed by ETK-node (to read the content from that TXT file). With ETK node you are free to adapt the given TXT file format (delimiter, number of columns, length of columns, &hellip;).&lt;\/span&gt;&lt;\/p&gt;&lt;p class=&#8221;MsoNormal&#8221;&gt;&lt;span lang=&#8221;EN-US&#8221; style=&#8221;mso-ansi-language: EN-US;&#8221;&gt;For running LS-PREPOST in batch please see &lt;\/span&gt;<a href=\"https:\/\/innovationspace.ansys.com\/knowledge\/forums\/topic\/how-execute-an-ls-prepost-command-file\/\">&lt;span lang=&#8221;EN-US&#8221; style=&#8221;mso-ansi-language: EN-US;&#8221;&gt;How execute an LS-PrePost command file? | Ansys Knowledge&lt;\/span&gt;<\/a>&lt;span lang=&#8221;EN-US&#8221; style=&#8221;mso-ansi-language: EN-US;&#8221;&gt; or in the Ansys LS-DYNA help:&nbsp;<a href=\"https:\/\/ansyshelp.ansys.com\/account\/secured?returnurl=\/Views\/Secured\/corp\/v232\/en\/lsdyna_prepost\/lspp_ug_cmd_index_command.html\">LS-PREPOST | Commands<\/a>. &lt;\/span&gt;&lt;span lang=&#8221;EN-US&#8221; style=&#8221;mso-ansi-language: EN-US;&#8221;&gt;Please read in the optiSLang user&rsquo;s guide how to use the ETK node:&nbsp;&lt;\/span&gt;<a href=\"https:\/\/ansyshelp.ansys.com\/account\/secured?returnurl=\/Views\/Secured\/corp\/v242\/en\/opti_ug\/opti_ug_etk_nodes.html?q=ETK\">&lt;span lang=&#8221;EN-US&#8221; style=&#8221;mso-ansi-language: EN-US;&#8221;&gt;ETK&lt;\/span&gt;<\/a>&lt;span lang=&#8221;EN-US&#8221; style=&#8221;mso-ansi-language: EN-US;&#8221;&gt;.
