Good Afternoon Community / Werner Exinger,
Attached is copy of the file that the community was helping me to resolve previously. My goal this time is to calculate alpha as shown in the worksheet. I develop a routine for alpha_v, but my results are not the same as the author whose result is reproduce as alpha_1, with the same 3 X 3 pile group. Would anybody be kind to tell me what I am doing wrong.
Regards,
Boyer
