I was trying to make some decorative icing or frosting for food and thought I'd share a setup for you. In this scene, the inflow object is shaped like a star. You can think of this as a cake decorating icing tip. Make any shape you like. The star follows a path and emits fluid as it travels. The settings of the domain provide for an almost static environment although you will find that the icing drifts slightly as time passes.
The cache resolution affects the detail of the icing as can be expected, however, you don't need the highest settings to get decent results.
To use this file, selet the domain object and bake the fluid simulation.
