Gas wrangle and include functions Jan. 5, 2023, 5:48 a.m.
Revisiting this question.
The problem persists if more than one field is being used/manipulated. It seems that the DOP Data parameter only allows one field at a time but if the function refers to say @temperature as well as @density it won't work. Using multiple inputs doesn't solve it either.
What's the trick here and why do I have to jump through so many hoops to access and modify fields in external VEX functions? I don't see the logic behind it especially since it does work in a SOP context.

I tried to simplify it. So consider the following function:
In a SOP wrangle, on a density field, the following code will work as expected:
But in a dop gasfield wrangle it won't.
I'm wondering if it has to do with solver-space. Maybe v@P won't work the same way? Or this new stencil field thing causes problems?
It might have to do with the Input Data settings but not completely sure yet.
Edit: nvm, it's the input settings. They have to be on DOP data and refer to themselves.
float test(vector pos){ return 2.0*volumesample(0,'density',pos); }
In a SOP wrangle, on a density field, the following code will work as expected:
#include <test.vfl> //@density *= 2.0; // this will work in a gasfieldwrangle and volume wrangle @density = test(v@P); // this won't work in a gasfieldrwangle but will work in a volume wrangle
But in a dop gasfield wrangle it won't.

I'm having an issue with using my own vex #include functions in gas wrangles.
When I test the functions in a normal volume wrangle in sopland they work as expected but when using them in a gas wrangle in dops it's as if the functions aren't used or evaluated. If I use them in a sop solver inside dops they do work again. The functions take standard arguments such as v@P, @density or float/vector and don't refer to anything external to the dopnet. Does anybody have an idea what might be going on?
