The exact error message is:<\/p>\n<p> &quot;Error in command AQWA.Start: No value has been assigned to the output parameter workbenchConnection after completion&quot;<\/p>\n<p>My output parameter is the maximum value of a paremeter vs time plot in a hydrodynamic response but is arbitrary, as a post-solve python script pulls all the actual results I want and saves them in an external file. This error also stops Workbench from running throuhg the design points, which is obviously annoying as each batch takes around two days to run and I lose however much time occurs between the error and me checking up on Workbench. This error has happened several times now, I have tried creating a &quot;clean&quot; file with no links to previous versions, but it didn&#039;t help. As far as I can tell, it occurs arbitrarily and is not due to user input, as the PC running the simulations is left unattended.<\/p>\n<p>Does anyone know what might be causing this error, and how could I resolve it?<\/p>\n<p>I have the detailed error message saved if it would be of any help diagnosing this issue, I can post in a comment below.<\/p>\n<p>Thanks in advance, <\/p>\n<p>Jeremy<\/p>\n","protected":false},"template":"","class_list":["post-162759","topic","type-topic","status-closed","hentry","topic-tag-aqwa","topic-tag-error","topic-tag-workbench"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"Hi,I&#039;m getting a weird error when running several Aqwa simulations through Workbench via design points.
