hello there, can anyone help me to define the correct boundary condition for 3d desktop computeer.
when i run this model in fluent it show the temperature around the casing not inside the component. please help me.... regards juju |

well what type of geometry you have chosen? if inside the geometry have not been meshed, so there would be no result for that region to show! if the geometry is meshed, usually it is defined as a separate zone and the display is done as normal.

thank doki, 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. |

well maybe there is not enough momentum to generate a flow, or the solution have not progressed well. also the solution is sensible to large mesh sizes.
