<p class=”MsoNormal”><span lang=”EN-US” style=”mso-ansi-language: EN-US;”>Hi euklidespl,<\/span><\/p><p class=”MsoNormal”><span lang=”EN-US” style=”mso-ansi-language: EN-US;”>the LS-Extractor tool can be used to extract histories (signals: values over time) or scalar Responses from LS-DYNA <u>binary<\/u> result files (eg. d3plot, binout). 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.<\/span><\/p><p class=”MsoNormal”><span lang=”EN-US” style=”mso-ansi-language: EN-US;”>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, …).<\/span><\/p><p class=”MsoNormal”><span lang=”EN-US” style=”mso-ansi-language: EN-US;”>For running LS-PREPOST in batch please see <\/span><span lang=”EN-US” style=”mso-ansi-language: EN-US;”>How execute an LS-PrePost command file? | Ansys Knowledge<\/span><\/a><span lang=”EN-US” style=”mso-ansi-language: EN-US;”> or in the Ansys LS-DYNA help: LS-PREPOST | Commands<\/a>. <\/span><span lang=”EN-US” style=”mso-ansi-language: EN-US;”>Please read in the optiSLang user’s guide how to use the ETK node: <\/span><span lang=”EN-US” style=”mso-ansi-language: EN-US;”>ETK<\/span><\/a><span lang=”EN-US” style=”mso-ansi-language: EN-US;”>.
