I want to do a fluid-structure interaction simulation with immersed boundary method. I am confused with the LS-DYNA available in ANSYS workbench. Based on an old user guide (2017) I found, it mentioned that workbench LS-DYNA cannot handle two-way FSI problem. Is this feature included in the new version of Ansys?<\/p>\n<p>If not, is it true that the FSI problem can only be done via LS-RUN? Can I use Ansys product launcher to call LS-DYNA solver to run FSI problem directly?<\/p>\n<p>I am also curious about whether you can use ANSYS-LS-DYNA to do preprocessing. I noticed that you can export k files from workbench setup for solids, can you do that for fluid as well? Can you export user-defined material from Ansys to k file?<\/p>\n<p>Thanks!<\/p>\n","protected":false},"template":"","class_list":["post-307404","topic","type-topic","status-closed","hentry","topic-tag-2-way-coupled-fsi","topic-tag-ansys-workbench-ls-dyna","topic-tag-ls-dyna","topic-tag-ls-prepost"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"I am new to LS-DYNA and have a couple of questions about LS-DYNA and its relation to ANSYS.
