      Workbench always does a sequential thermal-structural analysis when temperatures are applied in a structural analysis. 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’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.
