Air flow simulation in server

hi
i am using simscale for air flow analysis in server
but i am stucked in simulation step i want to flow air through server and reduce the temp of processors . but the error said that electric matrial or properties add please see and suggect what can i do for resolving issue

Hi,

From the error message the issue seems related to the Joule Heating module that you have enabled.

How are you setting up the heat dissipation of the servers? If you already have a power source under advanced concepts, you normally would have Joule heating off.

If Joule heating needs to be on, then you have to define where the current goes in, where it goes out, and at least 1 face (not a contact face, though) with a non-zero potential. These would all be “Wall” boundary conditions.

Cheers
