Scratch Posted July 31, 2012 Share Posted July 31, 2012 (edited) Hey there, I'm currently going through sidefx great waterfall tutorial, and I saw the Instructor use certain fields like the velocity field, the surface field, etc. information source for further effects. Since these fields come in handy when you want to create additional things like foam (which is shown in the tutorial), I wonder if there are even more such fields available? I know of these fields: *velocity *geometry *surface EDIT: found more *viscosity *density *divergence (can someone explain this one please?) Is there a place to look them up? I tried to search for them in the manual, but since I dont know for what to search in particular, it's kind of difficult. Maybe you guys can shed some light on this! Thx!

I think poking around the details view inside a fluid sim dopnet should reveal all the fields, as well as any other sim data you might be able to pull out of dops Quote Link to comment Share on other sites More sharing options...
Scratch Posted July 31, 2012 Author Share Posted July 31, 2012 I tried that, but it was kind of an information overkill at first. But you are right, I'll try again! Thx! Quote Link to comment Share on other sites More sharing options...
jkunz07 Posted August 1, 2012 Share Posted August 1, 2012 just quickly dropping down a shelf flip fluid tank I found the following fields: collision (scalar) collisionvel (vector) collisionweights (vector) massdensity (scalar) pressure (scalar) source (scalar) surface (scalar) vel (vector) viscosity (scalar) All the fields are created within /obj/AutoDopNetwork/fliptank/configureflip looking in there I found an optional divergence (scalar) field.

Scratch Posted August 1, 2012 Author Share Posted August 1, 2012 Thx for figuring this out! I aswell did some poking around in the Details View. It starts making more and more sense to me! Cool! Quote Link to comment Share on other sites More sharing options...

Oh and: DivergenceThe divergence of a vector function indicates how much of the field flows outward from a given point. Figure Y(a) shows a function that has divergence. Note that the divergence of a vector field is itself a scalar. If the vector field is a velocity field then a positive divergence implies the mass at the point decreases. Think of a tank of compressed gas emptying out; the volume of the container remains constant but the amount of gas inside the tank diminishes as gas flows outward. source Quote Link to comment Share on other sites More sharing options...
Scratch Posted August 1, 2012 Author Share Posted August 1, 2012 (edited) Interesting read! It is funny, for every item I strike on the list, two new ones get added. Hehe, I get the feeling that understanding this completely is a never ending story But I'm willing to dig on, so thx for the support!!
