Hi, i got a problem modelling an adiabatic system. i want to define my walls in a way that there is no energy given from the walls on the system (or let energy escaping from the system) but that the walls temperature is equal to the ones in the fluid cells near the walls. But my problem is that i think i have to put a certain number in the wall temperature textfield in the thermal conditions at the boundary conditions. is there a possibility that the walls have no temperature influence on the flow? Thank you in advance for your help.

h=0 will be ok

ah, now i understand, i am not allowed to switch to the temperature input panel, just stay at the heat flux and keep it at 0. Thank you for your kind help!
