Hi everybody !
I would like to create a model with 2 different temperatures at extremities, to see the heat flux between them. I created a load collector with a temperature at one side and a constraint at the other side. I shared the model file if you can check it. When I want to do an analysis, Hypermesh told me that the load collector with the temperature has no load... If I understand well, a temperature is not enough, but I don't know how I can solve this problem... I found a tutorial but it is with Abaqus and I use OptiStruct. Thank you in advance!
