Hi,
I updated the ThreeDTriaxialEngine for the last bazaar version.
The problem with "bex" (forces) access was related to the calling of
TriaxialStressController::computeStressStrain and
TriaxialStressController::ComputeUnbalancedForce from ThreeDTriaxialEngine.
As actually we don't need to call these fonctions in
ThreeDTriaxialEngine I removed them.
I will commit that as soon as I can.
Best,
Luc

Hi evrybody !
I fixed to ThreeDtriaxial test on the 0.20.2 version of Yade.
Bruno, I am not used to bazar version and I've never been working on it,
but since you say that it is newer than the one I have and currently
evrybody is developping it, I'm going to switch on it.

Hi,
I fixed the problem of sync() for yade 0.20.2 in ThreeDTriaxialEngine by
adding:
void ThreeDTriaxialEngine::updateParameters ( MetaBody * ncb )
Now yade can load the xml file and run it until it comes to write data
to the Wallstresses file:
For example, in my xml file I ask Yade to records data evry 50
iterations, and the current iteration in my xml file is 3221: Yade
crashes at the 3251st iteration but not for a sync() problem but rather
it throws me an error message related to The TriaxialStateRecorder.cpp
file
"TriaxialStateRecorder::action (this=0x9ec08f8, ncb=0xb44e220) at
pkg/dem/Engine/DeusExMachina/TriaxialStateRecorder.cpp:89"
the problem is located here:
void TriaxialStateRecorder::action (MetaBody * ncb )
{.
.
.
if ( ! ( Omega::instance().getCurrentIteration() %
triaxialCompressionEngine->computeStressStrainInterval == 0 ) )
triaxialCompressionEngine->computeStressStrain ( ncb );
.
.
.
In the Xml file, I ommited the TriaxialStateRecorder engine, and load it
in yade it runs with no crashes.
May be someone can Have an idea to fix this problem, Thanks !

I'm using the new version of yade 0.20.2, I replaced the triaxial
compression engine by the TreeDTriaxialEngine.
0.20.2 is quite old, given changes we've done recently...
Can you tell me how can I sync'ing forces in this engine!
Have a look at TriaxialStressController::applyCondition(MetaBody* ncb),
it is just a single line:
ncb->bex.sync();
you can put it to ThreeDTriaxialEngine, although that one doesn't access
"bex" (forces) at all; it looks like bug elsewhere, but you would have
track down where exactly is this bex being read.
