Freezing one side of a fluid container

[burleik]

Hi, I thought I would ask again. I have been working on this for a couple weeks without much success.

I am trying to create a fluid in a container that swirls a lot. BUT, I want the contents in -X of the container to hardly change at all - then gradually increase in velocity in the X direction. This works when I create a gradient velocity - but then the swirl option is disabled.

I should mention that the fluid container's density is created with an image map imported in paint fluids - and it is one end of the image that I want to preserve - with the rest of the image gradually swirling away.

I tried using the temperature gradient and have to go as high as 500 value in order to get one side to "freeze" but the hot side sizzles and falls apart. I upped the viscosity which helps but the smoke stays too much together - is gooey. I am also using damping.

Please help!

Maybe there is a good turbulence setting to approach swirling?

thanks, Kim

I thought of another possible solution, try a drag field set as a cube volume with and attenuation of 1 then make it's x and y scale much bigger than the fluids container and the the z (or whatever direction you needed) let the motion move. So the position would be at the one side that you don't want to move and it "fades" to the other side. you make the scales big so the attentuation doesn't effects the top/bottom and front/back.
Flieds work on fluids and I've used drag fields before. Most people stear away form them, but this might just work for you.

If you don't want the contents to move in X you could try setting the velocityScale X value to zero (and key it up when you want it to move ).
