The degree of freedom temperatures are solved first in the thermal analysis.  Then a structural analysis is solved with these temperatures applied as body forces (BF command).  The ds.dat file doesn&#8217;t show the thermal step, it just shows the results of the thermal analysis (i.e.: temperatures applied as body forces).  When the ANSYS input file is written (Tools > Write ANSYS Input file), the designed behavior is not to solve, so all workbench can do is write the first input file: the thermal one.<\/p>\n","protected":false},"template":"","class_list":["post-165311","topic","type-topic","status-publish","hentry","topic-tag-4685","topic-tag-general","topic-tag-mechanical-f-simulation","topic-tag-structural-and-thermal","topic-tag-structural-mechanics"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_wp_page_template":["default"],"_bbp_last_active_time":["3\/15\/2023 20:20"],"_bbp_forum_id":["27789"],"_bbp_author_ip":["23.56.168.180"],"_btv_view_count":["3483"],"siebel_km_number":["374171"],"product_version":["9"],"km_published_date":["2005-02-04T00:00:00.000Z"],"family":["Structural Mechanics"],"application_name":["Mechanical (f.
