Hey guys

Ive been trying this for a while now, but i still am not able to solve it.

Other than converting a grid to a volume and running a volume analyse sop, how would one calculate curl of velocity on a grid sop using an attribute wrangle.

Ive setup a simple grid and ran it thru a pointvop in which ive just plugged in the output of a curl noise vop into v. Now i just want to calculate the curl of v using just the attribute wrangle using neighbours() vex function.
So far ive managed to calculate the gradient of each v component, but the rest of math i cannot translate to proper code.

Any ideas?

p.s. does anyone have resources how to move from math notations to code

Thanks

Finally!

Thanks Andrew! You have saved me logging in and out of different desktops!

Cheers

I have had the same exact issue, and i still havent figured out how to solve it or what the issue is on KDE. I say KDE since houdini runs fine if i try and run it in enlightenment desktop or any other than kde. What i do now, which is annoying as hell, is when i start my laptop, i jump quickly into enlightenment source houdini from the shell there, run sesinetd since for whatever reason it wont run automatically, and then run houdini. As soon as its up i close it and move to kde and run it there and it works. I already submitted this as a bug tho sesi guys said they couldnt reproduce it. Im absolutely sure this has to do with a deamon or process in kde that stops license admin from running or houdini from runnig, tho i havent figured out yet which one it could be.

The problem is that houdini just hangs in the shell, there is no output i tried attaching a debugging process to it but i could not find a single output info that explains what the hell is going on.

I have given up so far since i dont have time to start turning services on and off and to debug linux with houdini to see why it wont run.

Hopefully this will get solved somehow

p.s. i should mention im running houdini on opensuse 13.2
