Define a temperature boundary condition for RADIOSS in HM

I followed the instructions of the tutorial RD-1080: Coupled Linear Heat Transfer/Structure Analysis. It is not clear how to define the value of the temperature boundary condition in HyperMesh. In the tutorial, only the value '0.0' is entered in the constraint panel, but you have to enter something for every dof-box (i.e. dof1, ... , dof6). So which one of these 0.0 values is the temperature? I already noticed, that the bulk data generated with the above mentioned tutorial looks like this:

SPC 4 2571 0.0

When I manually change the value '0.0' (=temperature value?) to some other value, the temperature boundary condition will be applied as I intended. The question is, how to do this in HyperMesh?

    seppaelae,

    When you uncheck all the dof in the constraints panel it is now understood to represent a thermal boundary condition.

    Once you uncheck all the dof boxes, select your nodes and then click on create, the constraints get created.

    Now go to card edit > change the entity to loads > select the constraints created in the previous step and then click on edit > now enter the temperature value in the D field.
