Hi everyone I will be documenting and experimenting on how to get the optimal mesh quality for an FSAE half simulation (and eventually full car) with focus on important parameters such as: Total mesh cell count - (dont want too many core hours / memory failure with 32 processors) Y+ Layer forma…

[image] dschroeder: I used meters (m) and not millimeters (mm) because i assume Simscale needs to have these numbers in meters (m). Although I have seen SimScale have many problems when using English vs SI units, I have NEVER seen SimScale ask for meters when it wants mm… In fact, I have I h…

I have to find a computer around here that I have never ran yPlusHistogram on it before and see if I have same issue…

I tried both and the 32 bit one had an error, the 64 said it cant the path [image] It could be the language issue. Or maybe that im running windows 7? i have no idea

Change directory in the terminal window using cd c:… to the dir where the ocx is, then type the command without any of the % items…

Is this what you mean? the OCX in the same place as the program? I have no idea :sweat_smile: [image]

ok haha, i was about to call an ambulance. Its late here and my head was about to explode. Thanks a lot for troubleshooting!

Darn, I think all it was, was that I forgot to take it out of debug mode when I compiled the project… I had to make it version 205 now and you can get the setup file for 205 here … Run that setup program and the replace all yPlusHistogram.exe files that you have put anywhere on your computer (like …

Success!! This is the plot from the full car simulation 1 layer BL at 3.4mm 1000 iterations - it seems i should have it run longer, it did not reach 1% stability [image] The Y+ histogram log is still running but so far it looks good. Ill update the final histogram when all faces are accounted f…

also on and off i am getting this error. When i re-click on the yplus_area.csv in the histogram program to re-calculate the Y+ it shows up. Not all the time though. When i click ok on the error box it closes the program but when i reopen it, it works agian. Just thought id let you know. [image]

Relax, I have duplicated your error on a new computer, I will debug this and get back to you here
