Body force always ends up with a bloated look

[stelees]

Hey there,

For an intro for a school assignment for my daughter we were going to have some fluid on a ground surface, rise up to for the word WET. The problem is there is away too many particles to form the lettering and it always ends up really blobby and a mess.

I was looking at the template file for body force and I can see the way it works when the fluid falls down from the object and rises up. Even then though, when you bump up the resolution for the grid the fluid doesn't fill all the letters evenly and they don't end up how they started.

Has anyone got any tips about rising up some fluid from the ground to evenly fill the text above it?

I have run multiple sims with the various options in BodyForce.. I though something like Spread Speed or Suppress Orb may have had impacts on this but I cannot seem to find the balance.

Thank you

It is key to have just the right volume of liquid to fill the desired volume without leaving gaps, and without overflowing it too much.

You could use the spread speed to space particles out inside the volume, but if there simply aren't enough particles, gaps will appear in the mesh generated from the particles.
If you have too much particles, the fluid simulation would not allow them to get too bunched up and will try to push them apart.

Can you show how your results look in motion and the settings you are using?

Cheers!

Thanks, I had a mess around with this and yeh, tweaking the initial fill did come up with a better result. We'll have a rethink of the grand plan of this one based on this info.

Thanks
