Vasileios Angelidakis proposed the following answer:
Hi weijie,

These are two different problems:

Problem 1: linear algebra error, iter:1 analytic centre did not
converge: The contact point was not calculated for one timestep. If it
is just one timestep, it is acceptable. If not, please provide a Minimal
Working Script, as in [1]. In any case, this is a warning and does not
cause a crash.

Problem 2: This is an error that we fixed just last week, regarding the
PotentialBlockVTKRecorder engine. Can you please let us know what
version of yade you use? If you compile from the source code yourself,
downloading the latest trunk would do the trick.

All the best,
Vasileios
