Dear Experts,

I have tried to run Tutorial 11 2-D FLOW AROUND TWO OBJECTS PASSING EACH OTHER. I am using STAR-CD 3.15 in a Windows 2000 machine.

I myself tried it several times. Then I requested two of my friends to check whether I was missing anything. But we could not make it run.

We noticed one thing that below the listing of cgrid.cgrd it is written

"As seen above, some commands in cgrid.cgrd make use of parameters A and I, which are supplied by user subroutine UPARM."

But I see nothing inside the listing of cgrid.cgrd such as A or I.

I will appreciate if you can help me work through this. If you had done it personally, it would be a great help if you could send it to me through emails which are given below:

Could you outline your problems in more detail? A and I are present in the file as A000 and I000 and I001 which are set in uparm.f: A000 is time step, I000 and I001 are the number of live cell layers attached to Object A and B respectively.
