Dear all,
I have been trying to implement the iterative loop used in the subroutine Ind_PropX for the calculation of the induction factors in a BEM code. However, when trying to demonstrate the equation for a’ I obtained a result that was slightly different to the Ind_PropX implementation. I attach a file where I wrote down my calculations.
Thank you for your help.
Regards,
Marco

Marco,
I apologize for not answering a long time ago. I was in the middle of a high-priority project and I am just now getting back to things I had to ignore earlier.
You must be looking at an old version of WT_Perf because we no longer include the Ind_PropX routine. Please download the latest alpha version of WT_Perf. You can get it here:

My apprentice, Andy Platt, is working on a beta version of WT_Perf and we hope to release in the coming weeks.
