Hi! How to set panes to a specified node? I tried hou.cd() and hou.setPwd() I'm triggering a python script from an hda. In the script I copy nodes and this leads to a change in the path of my panes - its focusing on the copied nodes. I don't want this and want to refocus on the inital node.

Hi, I have a parameter on my wrangle (operator list) with a realtive path e.g. "../Geo_*" . How to get an array of absolute pathes with all nodes matching ("obj/Geo_1", "obj/Geo_2", "obj/Geo_3", ...)

Hi! I've seen the compile block beeing used not only with loops but also wraped around regular nodes. When do I profit from doing that? Edit: To quick asked. The help explains it:

f@Alpha is for you

Exterior band voxels are from the colliders vdb. If the voxelsize of the collider is really small the "padding" - exterior band voxels need to be increased for collisions and also the sticking to work correctly. In my example file I have only a very thin narrow band for better speed. If you do somthing other than testig you should increase it a bit. I unlocked the solver only to enable opencl and to visualize the sticking. You could try to increase exterior band voxels even more. To only have it collide small padding is ok, but for the sticking it not only needs to know if fluid is inside of the collider, but also if it is close to the collider - this is where the exterior band voxels are really important to give it this padding and ability to check if the fluid is close. I will give it another test and try to make it stick more.

The exterior band voxels are not only important for the collisions, but also for the sticking. You should add more resolution, increase the exterior band voxels and tweak the sticking settings. Stick_Fluid_odforce.hipnc

It needs more exterior band voxels.

Try to replace : with ;

If you don't have collisions involved you can also retime using the gas upres.

thanks for your replies. I guess its just a viewport / too lowres problem.

Hi! sometimes when simulating fast moving smoke there emerges a flat surface on top of the leading edge of the smoke. I've tried to increase the upper padding of the gas resize dynamic, but it seems not to help. Can someone tell me how to avoid this effect?

To me this seems like a recursive loop. Maybe do 2 copy nodes. One for being the input and one for the output? But I'm no expert, haven't used the python node a lot.

it's always a good idea to set the frame rate of the timeline to something low and check what is going on in those subframes.

Thanks, it's working, but unfortunately it' s much slower than the sop solver workaround. fog_to_sdf_dops_compare.hipnc
