Foam Tool not working

TPouzol

Hi,
I've been trying to use the foam tool proposed with the VisualSPH.
I installed everything right (blender, visual sutio 2015, add on...) and followed thoroughly the tutoriel. However, it does not work and I can't guess why.

Have anyone tried it ?

Thanks

Here is the error message in the Blender console:

Traceback (most recent call last):
File "C:\Users\Kraeken\AppData\Roaming\Blender Foundation\Blender\2.79\scripts\addons\VisualSPHysics.py", line 435, in execute

Hi, it looks like the script cannot find the "h" value from the xml. Have you chosen the xml file generated by gencase?

TPouzol

Hi @Admin, no ! This was it !! Thanks
It could be nice to make the wiki on this point more clear
Chnage "XML: here, select the XML file used for the fluid simulation" to "XML: here, select the XML file generated by gencase"

Otherwise, the tutoriel is nice. thanks a lot.

Admin

Thanks for the suggestion!
I've modified the tutorial to make this step more clear.

@Admin I've been trying to do the same with one of my own simulation, but no particles are created...
Looking at the console there some nan and very small values so I wonder... I've tried setting all the min parameter to zero but no change.
Here is the console feedback:

Also here is a view of my simulation so it gives you an idea (dp 0.003)


Have you any suggestion ?
Thanks

Hi TPouzol,

after two years, I have exactly the same issue: with official tutorial, Foam Calculator works well, but with a my own case (veri simple case) I have same result as you in 2019

[Stage 10] Append new particles! Total diffuse particles: 0.

Have been you able to run correctly your own case?

If yes, can you help me?

Bye, Piero

Alex
