Hello everyone !

I have an weird issue with one of my sim... I have imported some objects in .sd and launch the sim;

here is the result :





as you can see it is a bit annoying.

BUT ... I have correct it, I think that it will be great to share the solution of a simple problem...

My object is open and the .sd export didn't see it, so in RF the volume type was in "solid inside" mode; i believe that it take the bounding box instead of the real mesh...

So, to solve you problem, just put the Volume > Volume mode in shell mode !

I hope that it will be useful to someone !

Happy simulation !

Hey,

Could you send me the sd file to check here?. Is it possible that you have removed some information from the geometry before exporting to SD?

Yes certainly :

Maybe it's best to upload the scene too, to get a better idea of your settings.

And here is the scene :

I don't know why but I can't have any good simulation with these parameters, I just want some little movement in the water... If I try to increase object friction branwidth or interaction factor it begin to jitter... Am I doing something wrong ?

I have also tried to increase the number of cell but it was not better...

Thanks for helping me !

Hey,

you forgot the geometry. I need to see the geometry to know how it is affecting to the fluid.

luisM.

Yeah, you forgot to include p61_start........sd

Oh ! My bad, I have uploaded the wrong file : here is the .sd :

I have just rename the file, so you have to reload it

Thanks for helping !

We had a similar issue here. Thing was the object's normals had been flipped. Correcting the normals again did the job for us.

Hey,

A couple of things here.

Florian is right. You have flipped normals for your objects and they are voxelizing in a wrong way. Also, you have geometry "perso_spatule....droite" incrusted with the capeMerge. keep in mind that it could be a wrong behavior when the solver voxelize theses geometries.
