[nero's houdini] 20 H19.5 SOP Flip

[@kerimdemir275]

finally someone explained it smoothly, thanks for this tut. One question; we call flip boundary as sources while we work with emitter source but as we work with ocean surface we wire this node not to flip boundary input but directly to the flip solver instead. Why is that? When we use solver's input, when to boundary's? Thanks in advance. cheers

For sure They will change some node names soon. I also was thinking that this containers also gets the bound of geo like you. Thank you for the tutorial

Very nice! Few comments: 5. I understand you want to build the setups from scratch but if you create Ocean Evaluate with Configure Wate Tank then it already has the Size and Center parameters set based on a spare input(called Domain Geometry). So you can wire the start geometry to Ocean Evaluate's spare input and have correct Size and Center. Furthermore, it is important that the volumes created by Ocean Evaluate are a little bit bigger then the domain. By the coloring of particles you can see that the velocity is streak interpolated. Thus you are not getting proper velocity and surface values in the boundary layer(just outside of the domain) where it is the most important to get these values right. If you increase the size to something like 52,12,52 you might/should get better results. 9. You do not need to use the Bounding Box to cut out the border. It is done automatically if you have the toggle Container on and the second input wired.

thanks for the advice

It is possible to create a round tank or just based on bbox? I made one without the implicit bounds but it seems wierd

[@neroshoudini1495]

@@Bolaway Bbox,round tank,theoretically you can,but it supposed to be explicit

[@tomasskrivan3291]

@@Bolaway Yes you can create round tank. Just input what ever shape to Flip Container you want. If the shape is convex and relatively simple polygonal shape, then keep `Implicit Bounds` on (this should improve performance), if its non-convex or really complicated then turn off `Implicit Bounds`.

thanks for the tutorial really helpful, can you one about upresing and combining FLIPs?
