Bruno Chareyre proposed the following answer:
Hi
Vh==NULL usually is the result of overlapping spheres in the problem (not 
allowed).
Here, the list of ids 20002, 20003, ... makes me wonder if they are not boxes 
bounding the problem instead of simple spheres.
If so those numbers should be defined in flow.wallIds=[20002,20003,...].
