Hello,
in the situation you are (did you compacted the sample with 
autoCompressionActivation=True? I guess yes.) you can:

- go back and make a sample compaction with 
autoCompressionActivativation=False. This will not automatically save 
the simulation after the compaction phase. But with few lines you can do 
it by python scripting:

triax.autoCompressionActivation=False
while 1:
    O.run(10000,True)
    if triax.unbalancedForce<0.0001:
        break
O.save('CompactedSample.xml')

- if you want to use the .xml you already have, the only to force the 
code to NOT load traxially, is to put:

triax.currentState=1 
(https://www.yade-dem.org/sphinx/yade.wrapper.html?highlight=currentstate#yade.wrapper.TriaxialCompressionEngine.currentState)
triax.autoCompressionActivation=False

which is much less elegant, but should work for your needs.


Bye, Emanuele.
