hi everybody.can anyone here tell me how to set up boundary condition for 3d desktop computer modelling.

thanks with sincerity... juju

Can you please explain your problem (Fluent model) more.

thank rajesh, now i working to finish my degree research about heat transfer simulation in a desktop computer with heat generating components. in gambit i define boundary condition

inlet-velocity inlet

hdd-wall

fdd-wall

cdr-wall

cpu-wall

mboard-wall

outlet-pressure outlet ok..then i transfer into fluent n run i didn't get exact result.the simulation give no aiirflow and not reasonable.

Hi Juju, You say that the simulation does not give any airflow. Look at the definition of your velocity inlet boundary conditions. Also, in fluent, look at the surfaces you have defined, if the domain is properly defined (geometry constructed) for airflow inside the desktop computer model.

tq for reply

sorry to ask u further,what is the proper defined for inlet boundary condition
