CHOLMOD error

Asked by Ehsan Izadi

Hi,

I've filled a cuboid shape with spheres using internal compaction. details are here: https://answers.launchpad.net/yade/+question/240920

Now I want to use flowEngine to simulate erosion of soil due to water flow.
When I do one step of simulation with flow engine, I get this error:

CHOLMOD error: invalid xtype
CHOLMOD error: argument missing
Segmentation fault (core dumped)

---------------------------------

Note that my code works well when I keep flow engine off.

If you need to see my code, I can provide it.

Thanks,
Ehsan

Probably an inconsistent definition of the boundaries of the problem, but I will need to check your script to understand better Ehsan. You can send it to me directly, together with the stl file so I can test it.
