Hi,
I'd like to ask that how to use TW.triangulate() to calculate strain between
two states by importing the two samples at the corresponding states.
The approach of calculating micro-strain between state 0 and state 1 is
mentioned at [1], the main steps are as below:
###
O.load("test.yade") ## import sample
TW.setState(0) #store current positions internaly for later use as the
"0" state
O.run(100,True) #make particles move a little (let's hope they will!)
TW.setState(1) #store current positions internaly in the "1"
(deformed) state
TW.defToVtk("strain.vtk")
###
The above code works well during a simulation.
However, I have carried out a series of triaxial compression tests and I saved
samples at different axial strain levels (e.g. at strain 0%, 10%, 20%). I
wonder if I can use TW.triangulate() to calculate the micro-strain between
strain10% and strain20% (or any of the two strain states). If it is possible,
it will save a lot of time as I don't need to re-run all the tests again.
something like (pseudocode):
###
O.load("sample_strain0.yade")
TW.setState(0) #store current positions internaly for later use as the
"0" state
O.load("sample_strain1.yade")
TW.setState(1) #store current positions internaly in the "1"
(deformed) state
TW.defToVtk("strain.vtk")
###
Thanks!
