Hi Jan,
I calculate the displacement and the external work with these lines:
if(asymmetry==0){ dAX*=.5;displacement=2*max(negIds.size(),posIds.size())*dAX;}
externalWork += displacement*(sumPosForces+sumNegForces)/2;
The eslastic energy and the external work are equal in the pre-pic stage and
that is reasonable for me.
Now i have to modify the calculation of the damping energy. In fact with
NewtonIntegrator, the damped energy is calculated in all the particles. But in
my case, i have to calculate the damping energy in the particles that don't
belong to posIds and negIds.
Best regards
Jabrane
