Thank you for your feedback. I am on vacations but I will try to have a look to this example. It seems that the problem comes h5py. What is the...

Nice, Did you experience some failing tests?

Are you sure that your matrix is invertible ? This was not really checked previously.

Yes, if you work we dense matrix, the matrix is altered. It is rather classical to store LU factor in place. Normally, a flag is set if the matrix is...

just to understand. Lu does not seems to fail on ``` 3.127660e+00, 0.000000e+00, 0.000000e+00, -1.000000e-03, 1.000000e+00, 1.000000e-03, 0.000000e+00, -1.000000e-02, 0.000000e+00, ``` since ``` 3.127660e+00, 0.000000e+00, 0.000000e+00, -3.197279e-04, 1.000000e+00, 1.000000e-03, 0.000000e+00,...

The problem comes perhaps from the fact xNS contains inf and nan

With 2eea008accd290c74409605df32f3261d005e923, I do not experience your problem. I get this result: [result_example1NLDS.pdf](https://github.com/siconos/siconos/files/5544831/result_example1NLDS.pdf) 

The feature was disabled because it was not correctly supported by the simulation classes. Nevertheless, it must be a feature of the simulation classes to be able to change the...

Strange again. Normally, we should be able to insert a TimeDiscretizationEvent in the EventManager. We tried to build these classes without referring to a iteration number k. Perhaps, it is...

I just have a look to the EventManager class. It cannot work like that. We have to refactor also this part :-(
