The version 1.0 in CentrifugalPump is functional and might work well,
The version in Symmetrical folder is at study and compressed in the code in a symmetrical way throughout the operation calculate [(right and left) and (up and down)].
Trying to make more symmetry i have made a mistake that i will correct in the RealBasic Version at study, if you want to correct it copy the code from "Analisi_Vecchio" (old one) , the code to make the final calculation, and paste in the new version. I have no more the VB compiler so i can't do it, I will use RealBasic by the next versions.
Also the symmetrical one have a routine to calculate the best border, named "TrovaBordo", TRY IT!!!
Be patient and try yourself.
Best regards and happy engineering!!!
