Simple PFV case
Hi,
I have some experience with YADE, but this is the first time I am using PFV. I want to experiment with DEM-PFV. I am aware that there is an example by the name Odometer Example. I have 4 spheres. Each sphere is connected to its neighboring sphere. I want to apply fluid pressure at the center of my model (0,0,0) and have the spheres spread outwards due to the pressure. I have made an attempt, but I have no clue what I am doing (the PFV part). I get an error:
0 : Vh==NULL!! id=0 Point=0.5 0.5 0 rad=0.5
1 : Vh==NULL!! id=1 Point=-0.5 0.5 0 rad=0.5
2 : Vh==NULL!! id=2 Point=-0.5 -0.5 0 rad=0.5
3 : Vh==NULL!! id=3 Point=0.5 -0.5 0 rad=0.5
AREA <= 0!!

I will attach my code. Any help on this would be great.
Thank you soo much!
