how to you make liquid Explosion?

Postby da1x » Fri Oct 06, 2017 3:53 am

Im trying to make some kind of liquid metal explosion with as little polygons as possible.
Ive manage to make something for the start which I am ok with it but I dont know to make the drops like in the end of the video.(bits and piece all over the place.)
I think is because of the low polygons settings that made it into a one big mesh.

Video around 1:12~

We need more information about your settings. Can you post (write here in text) the settings you use for the emitter, especially the Particle Density settings? And the settings you are using for the Mesher? (Polygon Size setting, ans are you using any Mesh Filter or Mesh Thinning settings?)

It does look like your Mesh | Polygon Size setting might be too high, but if that were the case, its hard to see how you obtained the result in your first image.

Im new to realflow and simulation. Im sorry if my setting is all messy. Thanks in advance.

My emitter settings are:
Resolution 1
Density 200
Int Pressure 1
Ext Pressure 20
Viscosity 18
Surface Tension 0 to 500 using curve

Volume 0.5
Vrandom 1.0
Hrandom 0.2

My mesh setting.
Polygon size 0.09 to 0.6 (I want to keep the polygons as low as 30k max with alot of try and error I ended up making my size to 0.6 at the end.)
Smooth 50
Surface proximity 0
Thinnig 0.1
Relaxation 0 to 0.8 (I thought this will make the liquid more sticky kinda shape, not really sure if im doing this right.)
Tension 0
Steps 132

I tried to make the blast using crown, this might be wrong way to make it tho...
Crown1 strength 400
Crown2 strength 350
