Tutorial 5 - Primeros Objetos en nuestras escenas (Parte II)

[Draugmith]

Continuando con el tutorial anterior vamos a ver otra de las opciones de colisión que nos permiten los objetos en la escena y es la colisión interior, es decir si el fluido viene del exterior no colisionará con el objeto hasta que  lo intente hacer con las caras interiores del objeto.

Teniendo la escena del tutorial 4 vamos a las propiedades del cubo y en la pestaña de Particle Interaction (interacción con las particulas) cambiamos el metodo de Collision Normals de Both (ambas caras) a Inward (caras internas)





Vemos como las partículas en un primer momento atraviesan el cubo pero al colisionar con las caras internas del cubo interaccionan con él y van rellenando el cubo u objeto que tengamos en la escena.


Aqui tenemos un primer Video con el objeto cubo visible y en el segundo video con el cubo oculto al render por tanto vemos como se forma la figura del cubo con la malla de nuestro fluido

Hola Draugmith, amigo contigo da gusto aprender, a mi que personalmente me encanta RF, sigo al pie de la letra tus tutoriales y se me hace cada vez más fácil.
Un saludo y mi aplauso

aqui tienes otro seguidor mas para esta serie de tutoriales, sigue asi y me acabare olvidando del cinema ese.

Pues si, me uno a lo de que así terminaremos olvidandonos dell Cinema  , muchas gracias Draugthmit por brindarnos la luz tan fluida y líquida   

Saludos

Hola! I'm new in RealFlow...
I'm sorry but i can't speak spanish...but my cilen room-mate will traduce me....now he's spleeping..

I follow the tutorial but..
do you know how can I have a perfectly squared mesh inside the cube (pt.II) ?
I made infinite tries...
Finally I reached best results importing an hi-poly cube with these values for the emitter:

  10.0  resolution
18000 particles
20000 density

(scale 1.000)

the mesh generated has the shape of the cube but is always a bit rounded on the borders...like its trying to be a sphere...
What's the best way to have a PERFECT CUBE with liquids?! is it possible?
Btw is a long simulation...

Thank you for reading in English...

hasta luego!

[Draugmith]

Hi....

first of all, what´s your 3d software ??

you can try to increase your resolution for example 100 or 200, if you do that remeber to change yor max particles to 200.000 or more....

remember : the density of water it´s 1000   

best regards

[pignaccia]

Thank you Draugmith!!

now i'm trying with

100 resolution
2000 density
and

1500000 particles.....maybe is too much?!? 

I go sleep...here it's 7.00 a.m. now...
I passed the night on realflow
but first leave my computer with the simulation!

thank you..i 'll let you know!

[Draugmith]

 

we wait your results 

[pignaccia]

hey.
I tried with this settings..

resolution 100
density 2000 ( i need something different about water, like fuse metal...)
particles 1000000

my computer stayed on the 36th frame for an hour..so I decided to abort the simulation!

Now it's simulating the same with 500000 particles...will see...

I tried to improve the resolution but it's too hard for my CPU. I will remain with 100 and will play with the other settings...

I will let you know!

AHHHH... I use cinema 4D.

thanks all you will replace in english!
see you soon!

[Draugmith]

Remember, if you use Cinema4d the correct scale to work with Realflow4 it´s 0.01 or 0.05)   

[pignaccia]

AH ok..thank you!
I changed the scale to 0.05!
but is that different about hardware performing or is just for importing in c4d?

Now I insered a ObjectField for the cube.

is there anything I have to know when importing object.sd (the cube)? Need it to be converted?

with changing the parametres of the emitter something goes wrong everytime...

Now I can't increase the resolution...the system crashed...
my last safetly configuration:
resolution: 10
density 2000
press. 1
ex press. 0.1
viscosity 10

are there any other methods to square the cube?
maybe with some attractor?

do you think is it an hardware trouble?

thanks for patience!
I should leave this effect but i need it for an animation...just that effect with liquids(maybe not )!
So I want it to be perfect, you know! 

p.s.
if someone interested i will post in spanish with my room-mate's help!

excelentes tutoriales, muy explicativos e aprendido rapidamente
felicitaciones y gracias

Aparte de aprender realflow estoy recordando un poco mi olvidado inglés
