Yes its supposed to be a little viscous, like close up milk/blood running over the ground. the line is really strange, i mean its just a box. Somehow the slight rotation messes up the collision.

thanks for looking at my file. i changed the surface extrapolation because i got this edge below my sphere(pic1) but your absolutly right the default value works mutch better for the sim. I took your file and upresed the particle seperation(fluid object) to 0.005 and now i get really weird collisons (pic2). ah and with the 350 on the static object i just wanted to get sure that the collision resolution is not the problem. I looked at the collision representation on the fluid object, this is what it looks like When i disable the rotation of the collision box, everything works fine... i attached the new file Thanks guys for the help!! fluid_collision_2.hip

hi, I cant get my fluid to smoothly flow down a -.5 rotated flat surface. After a few frames it will flow down a bump and get faster. The fluid runs smoothly on the same surface without the rotation. My guess its a problem coming from the rotation and its voxel interpretation. I really pushed the collision resolution and tried different collision methods(static object/ source volume), still the same problem. I'm using Houdini 13.0.7 but also checked the file with apprentice 15.5, still the same problem. Has someone faced the same problem? I really would appreciate every help, thanks in advance Martin .hip is attached fluid_collision_1.hip

This sidefx class helped me a lot this one is also nice (dont forget to activate subtitels)

Hi, I'm playing around with rbd and try to automatically fracture my pieces based on impact data. To identify the impact data's corresponding rbd piece, I use the impacts primnum attribute. That works just fine until it fractures the first time. Because the pointnumbers changes, it doesn't work anymore. My question, can I get the impact data to pick up more information from its "source piece", for example the name attribute or any identifying ones. I attached my scene. Cheers, martin impactfracture_odforce_01.hip

I updated the file to h13 a time ago. Works also fine with H14. The advection mode is BFECC, with McCormack the results weren't that nice. pyro.hip

Dont know how good the result looks but CMIVFX just released this snow tutorial...

Hi this is a great thread. Here is my approach to the day 5 challenge, with a little addition. I wanted the object to only color geo on the outside of itself and also get it to work without SDF.

Can the IndieEnginge serve as a mantra render license or is it only able to generate ifd's?

Here is the answer. http://www.sidefx.com/index.php?option=com_content&task=blogcategory&id=219&Itemid=382

I think there will be a 13.5 release. At least the Documents section at sidefx.com has an url for 13.5 http://www.sidefx.com/docs/houdini13.5/ Only for beta users. But stil,l no link for 14.0

Hey maybe this sidefx masterclass on FEM will help you...

Hi, i attached your modified file. I just used the existing "transform pieces" digital asset to do it. testProxy_01_back.hip

I would like to be able to simulate with vdb volumes

Hm i think you are right with all your assumptions. I think the dop import uses the lowres sim still in catch. Probably it would be smarter to write out the point representation of the pieces and copy the high res ones onto them. I must say i m also a beginner in the rbd topic so I'm not really sure whats the "best" way.
