yPlus Histogram program as a new metric for y+ mapping evaluation


#1

I did this work a couple months ago and I have decided to do a forum post to make this new metric more available for people that are searching for a better way to evaluate their yPlus mappings.

Here is a project of mine that explains why my new yPlusHistogram program exists.

Below is the zip file for yPlusHistogram.exe v2.05 setup program… (extract all file in zip to a temporary folder, then run the setup.exe file in that folder)

This v205 includes the new ORSI by moving average feature (and it will work if you use the European decimals and thousands separator in your Windows setup) !!!

Please see the README.txt file(inside the zip file) for further instructions if needed:

I promise, no bad things in my .exe file :innocent:

Here are a couple of videos that show how to use it:

NOTE-THIS IS NOT SHOWN IN THE VIDEO; As of Jan-2020, for some unknown reason, before you export the csv file from ParaView, you have to drag the yPlus data column to the left of the Area column so that the yPlus data precedes the Area data in each line of the csv file…

Have fun :sunglasses:

You’re the man Dale! :slight_smile: Glad to see you back :wink:

Cheers and let me know if you need anything!
