To do this, we need a fluid object and an obstacle object. To make the other objects go into the "Wireframe" viewport.Īs a basic start up for your experiments with fluid simulation, I am going to take you through a small demo in which we drop an object into a pool of water, creating a splash. Due to this you should change the "End" frame to "96", under the "Timeline", because the standard setting is "4". Under "Time" you can adjust how many seconds the fluid animation will take. These will be explained as they become important.
Each one opens a different set of settings. Also in that tab, you'll see 3 sub-sections, "Fluid World", "Fluid Boundary" and "Fluid Particles". All the fluid physics will be calculated inside this cube.
Find the button that says "Fluid", and click the "Fluid" button to enable the function. With this cube selected, go to to the Physics context of the Properties window. Don't make it too large, but not too small either, let's say 10 times bigger. This will eventually be set as the volume in which all of the fluid simulation occurs. One can imagine how much time it would take Blender3D to think about everything in the infinite space of a 3D world in terms of fluid objects and deflection, so we obviously need to cut down on that size. This tool looks unnervingly complex at first glance, but this tutorial should clear it up for you. Wouldn't it be great if we could get an accurate physical representation of this liquid in Blender? We can, using a tool called Fluid Simulation. Water is without a doubt one of the most important compounds in our lives It covers about 75% of the earth and is therefore incredibly important in quite a few Blender animations.
