Simstrat not running for long time series (>68 years)

[JFeldbauer]

I try to run a single Simulation for about 100 years with daily forcing data and ran into an issue where Simstrat will act as if it successfully ran but actually no output is generated. I tried changing the "MaxLengthInputData" parameter but this did not change anything

I use Simstrat version 2.4 (using the SimstratR R package), an example output of such a run is:

But the output file T_out is just the initial temperature profile and the whole run takes less than a second computation time.

system.time(SimstratR::run_simstrat("Simstrat/", "simstrat.par"))
   user  system elapsed 
  0.008   0.012   0.020

If needed I can provide the model setup to recreate the problem.

All the best, Johannes

Hi Johannes,

This is a bug and it will be corrected in the next few weeks. Thanks for pointing this out!
