Hi uskaborja, This is Sumit from Indian School of mines,Dhanbad.I got your id from this thread http://www.egpet.net/vb/threads/3382-S-T-A-R-S-%28CMG%29-Reservoir-Simulator .I am currently working on my final year project on "ASP simulation using STARS".I want some little guidance on how to use STARS for this purpose.I wonder if you can help me with that.There is no force,you can say no and that will be perfectly understandable but if u can find some time to help that will help me a lot to get me going in my project.Any little assistance will be highly appreciated Let me know if you can give me some guidance. Thanks and regards. SUMIT KUMAR RAI,ISM Dhanbad,India sumitkumarrai.ismu@gmail.com
