3 years ago Hi Declan – this probably wont work (sorry)… I’ve tried it before and it’s a classic sensitivity to initial conditions situation. You won’t get the same number of DP saved to the file as stored in the memory (double) for all the parameters… If you can – it might work, but suspect if just one wee thing is a bit different the overall outcome will be similar – but not the same. Deterministically non-linear model..

Summary
CL has option to load in previous model state and being the simulation by initialising water depths, sediment matrix and flow vectors (although don't think flow vectors was completed in CL?). This would be useful to re-implement in HC, so long runs can be broken up to fit into to wall clock limits on HPC etc.
Acceptance criteria
- [ ] Split the test simulation into two halves.
- [ ] Restart the second half of the test simulation from the output files written in Part I
- [ ] Verify that restarting from midway output files produces same results as a simulation run all the way through in one go.
