Just to clarify, the flag I turned on for the compilation is
CHOLMOD_GPU, which is not related to this issue, my bad.

Below is the cmake command and the cmake command output of YADE-2019.01a

>and compile with CHOLMOD flag ON

What does that mean? We don't have an explicit cholmod flag during
compilation. Please indicate your cmake command and cmake command
output.

>Yadedaily 2020-ish

What does that mean? I dont think we have a "Yadedaily 2020-ish" branch.

Status: Answered => Open

Hien N.G. NGUYEN is still having a problem:
Many thanks for the comments.

@Jerome: I've never done that before, can you please show me a simple
example?

@Robert, as you suggested, I downloaded the source code of Yade 2018.2b
and Yade 2019.01a and compile with CHOLMOD flag ON, the script runs fine
with useSolver=3 and gives me the correct stress values.

However, for Yadedaily 2020-ish, the stresses still act strangely no
matter how I configure the useSolver value, I tried both values 0 and 3.

Status: Open => Answered

Robert Caulk proposed the following answer:
>>2) useSolver was set to zero because Yade 2018.2b gives me error about
not-compiled CHOLMOD when I used 3, but I think I should ask in another
question about this issue.

Please recompile correctly with CHOLMOD and redo your comparison using
useSolver=3 or 4. useSolver = 0 is really not supported or check tested
anymore.
