have you attended the spray and combustion and moving mesh training course? Most of the answers are there.

cd-adapco also have a knowledge base in the site where you download the software, most of the answers are there as well. You can search the knowledge base to have the answers. You need to ask your account manager to enable you access.

good luck

Remote diagnosis is rather difficult.
