  1. checkpointing does not work with PUML meshes (the simulation always starts at t=0)
  2. checkpointing does not work with RS friction (as the state variable is not checkpointed).
  3. checkpointing does not work properly (even with a netcdf mesh) if the friction is initialised with ASAGI.
  4. checkpointing is not well documented in readthedoc (easy fix).
  5. Checkpointing with attenuation is not working properly

actually 3 is probably due to the fact that the 'smoothslip' variable is not checkpointed.

  1. Partitionning is now saved in a hdf5 file, which should allow checkpointing with PUML meshes (and to compare fault and wavefield outputs from 2 simulations).
  2. the state variable is actually checkpointed. Yet is seems there is still a problem with slip and RS.
  3. documentation added

Checkpointing with attenuation is not working properly. I got the following error when writing the first CP:
