Field around obstacle - fluid can't touch it?

Post by Pole » Mon Dec 17, 2007 7:47 am

Made a pool, with shallow water in it. Have an object (obstacle) slamming down to the bottom, making the water splash all around. When the water comes back, there is like a field around the whole object, so the water doesn't touch the object...!

I got one suggestion from the chat channel to scale everything up, but that just made the field even bigger...

Any other suggestions?

Big Thanks in advance!!

Nice link!! Very good guide for a bunch of parameters... still didn't mention anything about having to scale everything down... but since scaling up caused it to get worse I guess scaling down would make it better... but still don't think it will get close enough to look good...
I will try the scale down thing next time I get some time...

Many thanks for the link and for the suggestion!

Nah... I just shrunk everything a whole bunch, and it is still pretty much as bad. Can still clearly see a big space between obstacle and fluid... :(

I wonder if it is just a setting instead I need to change or something??

Anyone?

THanks in advance!

Pole,

My 'scale down' was in return of your conclusion:

An alternative might be, to make a substitute 'obstacle', which will than be smaller than the mainObject. The mainObject is parented to the substituteObject and the substitute is of course transparent...

If you ask me, the fluid-system is able to do what you want..., continuing now 'to-get-it-done' is already helping you out next-time... :)

Hope this helps,
Niels


ps.
If you want to try-out using the fluidsystem, use a separate .blend till all parameters will become logical-values... Then you'll know if it is 'the fluidsystem'... ;)

Have you tried increasing the domain resolution?

mess with the obstacle buttons a little. make the domain bigger. what helped me is to make the obstacle half/half or something. its bounds would only be the actual object.
