Re: [Question #659557]: Flow engine working randomly with CHOLMOD

 

Question #659557 on Yade changed:
https://answers.launchpad.net/yade/+question/659557

Luc Scholtès gave more information on the question:
Typically, here is what I get:

Qin= -308.240063332  Qout= 0.0 
Permeability [m2]= 0.0  || Hydraulic conductivity [m/s]= 0.0

and when I open the vtk file, I can clearly see 0 pressure values in
every cells (1e-16) and high velocity values on several cells located on
the boundary where the pressure head is applied (1e5).

Regarding my laptop configuration (it is quite old but still running OK,
bought it in 2012):

Dell Precision M4700
Memory: 77 GIB
Processor: Intel® Core™ i7-3840QM CPU @ 2.80GHz × 8
Graphics: Gallium 0.4 on AMD CAPE VERDE (DRM 2.49.0 / 4.10.0-37-generic, LLVM 3.8.0)
OS-type: 64 bits

Another interesting fact: I always get a wrong result (or no result if
you prefer) when I am launching this script while another simulation
(different, no flow involved, working alright) is running at the same
time... Is it a sign that my laptop is at the end of its carreer :)
