Hi,

This is very useful information and I am able to resolve my error now. 

I have another question. How to define % vol of gas( or volume fraction) and air in a given volume using *CHEMISTRY COMPOSITION keyword or is there another way to define same. I need to define two different CHEMICAL COMPOSITION for inner volume and outer volume. How can I control the volume fraction of gas (say 10-30%) for inner volume. Refer example shown below.
