dummy thermal load

[John]

evening to all, I would like to succeed in shaping a contraction in a solid that has as a solid45 element, ansys assistance has limited itself to telling me

dummy thermal load to apply a contraction

How do I apply strength? I press that it would be better to avoid codes then use the graphical interface, because I have to deal with a solid from the rather ruddy geometry
thanks in advance

I looked for the way to change the message but nothing, but the late hour and ansys are not a right mix...
cmq I was doing one of the many tests and I wanted to add that the contraction I would use to create a force we say "structural". . .
I have seen that you can choose between the properties of the element the thermal expansion, but are still there
