Hi, all:
I am recently having such kind of problem, I have two costomized engines, one
is called "ConvergenceEstimator", which is used to evaluate some
maximumUnBalanceForce over the contactForce ratio (this will return a CCValue
to evaluate whether the whole particle system is close to equilibrium), then I
have another engine "DampingAdjustment" designed to change the initial
simulation parameter, in my case, the damping coefficient, for example, from
0.3 to 0.4.
I have one piece of code in the preprocessor (similar to SDECSpheresPlane)
which looks like this:
///--------------------
...
rootBody->engines.push_back(ConvergenceEstimator);
rootBody->engines.push_back(DampingAdjustment);
///--------------------
This means my DampingAdjustment Engine needs the return values of the previous
engine, I need to have something in DampingAdjustment like(I think should be in
DampingAdjustment::applyCondition(Body* body)):
if (convergenceEstimator->getCCVaue() <=eps)
dampingCoefficient = 0.3;
else
dampingCoefficient =0.5;
I think this is purely a programming problem, how to access the
ConvergenceEstimator which is the other engine?
I hope I have made my problem clear. Thank you very much!
