The file should be the same as the file written for CONSTRAINED_BEAM_IN_SOLID according to the manual. The file is presumably in LSDA format, but I don&#8217;t know what that means precisiely. I tried opening this as &#8220;Fringe&#8221; data with LSDA format in LS PREPOST, but PREPOST just crashed when I try to do this.
