Hi guys,
as discussed with Bruno in Barcelona I need different non-viscous damping
coefficients for different materials. I introduced this capability by adding a
variable damping to the base class material which is initialised with NaN. The
body class has a function getDampCoeff() and in NewtonIntegrator I use this
function in order to change the damping coefficients. When running some
examples
it seems that everything works fine. However, I just run 'yade --test' and it
gives me a seg fault:
testVelocity (yade.TestSimpleClump)
Clump: velocities of member assigned by NewtonIntegrator ... Segmentation
fault
I think I now where the problem is. In NewtonIntegrator I call something like:
if(!isnan(b->getDampCoeff())) dampcoeff=b->getDampCoeff();
where getDampCoeff() is defined in body.hpp as:
Real getDampCoeff() { return material->damping; };
I think the test doesn't have a material and therefore I get the seg fault.
Right? How can we fix this so that I can commit the code?
Klaus
