[Ansys14] Problem with steady-state thermal
 

Hello,
i have problem with thermal simulation in ansys. I have done couple simulations of device with coil. Diffrence between them are dimensions of some parts. First simulation went quite good but all the rest looks like only coil is heating up. Device is surrounded by air and is placed on big steel plate. Between all parts are bonded contacts. I have add convection in all parts of device (2e-4) and internal heat generation (1,36e-4). I don't know what was diffrent between those animations and why the results aren't the same. Also why i have diffrent time on Tabular data but maximum temperature don't change? Is that because of steade-state (non-transient) thermal simulation?
Here are screens from simulations:
