Active body - defining the density of water

[harald_martinoff]

Hi

I have a plastic object floating in ocean. the whole simulation goes good, but as I define the density of the object to 930 kg/m3 (as of plastic) I wonder were I can define the density of the water? Basically water is 1000 kg/m3, but this is salty water and as such 1025 kg/m3. Is it possible to define this in the Liquid simulation?

After working a bit with this I also have problem with getting my object to float on the water. I use the Phoenix properties to define the density of my object even as a cork (270 kg/m3) just to force in floating, but it sinks into the water. I start the simulation with the object hanging approx 10 cm over the water surface, object falls down and sinks into the water. When I use the plastic density (that is 930 kg / m3) it just stays 50 cm deep into the water (My object is 1,9 meter x 1,2 meter). I also tested out the "Active Bodies" and heigthen the Fluid Dens Multi to 2 (2000 kg /m3) and even then my cork object sinks into the water and stays sub merged. Any one know something about this?

I m not able to get this to work anywhere close to a real situation. I have an object made of plastic. It is an irregular object, a "floater", a buoy kind of thing, but it just sink.
Water is set to 1,025 in Active Body dialog (salt water) and the Buoy thing is even set to Cork (270 kg/m3) and it just sink and stay below surface

Hey,

Could you send us a simplified scene, so we could check it?


Thanks!

Hi Slavina

Thanks for following this up and I will get to it, but now deeply into another project and I dont have time to make a scene like that. Will follow it up!
