Hello everyone,
With Converge CFD, I am working on the combustion analysis of a diesel engine as a closed cycle. In other words, I am working for the case where the valves are closed.

I am trying to overlap the CFD results with the in-cylinder pressure graph at the time of compression, but I could not get it to overlap as I wanted.


I checked my compression ratio for this.

I even reduced the compression ratio to the effective compression ratio.

Still no overlap occurred.

While doing research for this, I learnt that specific volume and specific pressure values are effective.

However, I do not know how to change these values, is there anyone who can help me with this?
