[deprecated list] Timer works, but no motion

[Anton Gladky]

Hello all!
I am playing with YADE, and sometimes when I start simulation no motions I
see. Timer is working but the picture is static.
Especially, when I generate "Rotating cube" example, it happens often.
What can it be?

Change the simestep by hand to something like 1e-2. I will put it to the
code also.

RotatingBox crashed here and I had to remove lines

rootBody->transientInteractions=shared_ptr<InteractionContainer>(new
InteractionVecSet);
rootBody->bodies=shared_ptr<BodyContainer>(new BodyRedirectionVector);

from RotatingBox::generate() to fix it. I will commit this shortly.

Vaclav

Thank you, Václav, for the quick help!

A several weeks ago I wrote about choosing the software for my tasks
simulation.
So it seems, I will use YADE for that. As less till the end of this year.
Then we'll analyze result and make final decision.
I hope I will be able to understand how YADE works and will try to develop
YADE project as well.

yes, that's too small timestep.

Why VecSet is crashing and only VecMap is working?

openMP needs linear-index access to the container. VecSet doesn't
reimplement the virtual operator[](unsigned int) which just throws in
the generic implementation.

I propose to delete VecSet, since using VecMap speeds up simulations by
about 30% compared to VecSet (that' why it is not the default any more)
and it will never work with parallel code.

yep, please delete it.
