Dear Sir,

I am trying to read cylinder pressure of an IC Engine, I could model the combustion chamber and run the case in FLUENT, but i could not read cylinder pressure. Some body please help me which option i should use to read this.

you can use volume integrals (in report menu) to integrate the pressure inside the cylinder and get the values.
also if you are willing to get the calculated value for different crank angles, you can set the same settings in the define/animation before running the case.

Hi,

I am new to FLUENT and i m trying to run the ICE cold flow simulation tutorial given by FLUENT. I followed all the steps given but still I am getting error after I apply the initial conditions:

WARNING: Unassigned interface zone detected for interface 21
WARNING: Unassigned interface zone detected for interface 26
Error: Init_Flow: unassigned interface_zones
Error Object: ()

What could be the possible problem is it with the mesh or case set up?
I assigned all the zone as per the tutorial.

Please help me with this.

Thanks,
Yashodeep

I have seen ur message today
initialization problem- it might be at interface_zones
if u can send the soft copy (pdf) i can suggest u.
