<p>Hello,<\/p><p>I have a model Static -> Modal -> Random vibration in Workbench. It is a large model, so I am expanding only the modes whose ratio of effective mass to total mass is greater than 1e-3 with the following code:<br>mxpand,none<br>SOLVE<br>FINISH<br>!<br>\/SOLU<br>antype,modal,restart<br>mxpand,all,,,,1e-3,,EFFM<br>modseloption,,,,no,no,no<br>SOLVE<\/p><p>I have the “Store modal results” set to “For future Analysis”. However, when finishing the PSD, I get the following error:<br>The result data for spsd is not contained in the result file.<\/p><p>I have used this same method with a harmonic and it worked fine.<\/p><p>What could be happening? How can I fix it but keep the part where I select what I want to expand?<\/p><\/p>\n","protected":false},"template":"","class_list":["post-388021","topic","type-topic","status-answered","hentry","topic-tag-Modal_Analysis-1","topic-tag-ansys-apdl","topic-tag-ansys-workbench","topic-tag-apdl","topic-tag-equivalent-stress","topic-tag-error","topic-tag-modal","topic-tag-psd","topic-tag-random-vibration","topic-tag-results"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
