¿any directions to make flip surface tension?

Recommended Posts

hi, there i just wanna know about some directions to make surface tension,  something exactly like this:

  right now im in houdini 12.5 i cant open newer files,  but some directions on how to make surface tension would be great,  i saw  a topic where they are using gas surface tension microsolver, but i just can make it work in 12.5  i dunno if it because is something about so new stuff...

Hola Arturo!

 

La implementacion mas basica de tension superficial es calcular la curvatura de la superficie del fluido (en el caso de FLIP, el "surface field") para luego usarla como factor de desplazamiento usando el gradiente (normal) de la superficie del fluido. As que si la curvatura es negativa (concava) la fuerza se ejercera hacia afuera, y si es positiva (convexa) la fuerza se ejercera hacia adentro, de esta forma a medida que el sistema avanze frame a frame todo intentara forjarse de forma esferica debido a la decimacion por curvatura, dando como resultado el efecto deseado.

 

Saludos!
