Hi all,

I am encountering further resistance with C-VSM, although my need for it is not critical. My simulation is currently crashing after a handful of iterations. Initially, I thought it was because of the depth synchro error, but that seems to be solved in #43050. Thus, the problem must be elsewhere. (I decided to spawn a new thread to make this specific error easier to find.)

Initially, the simulation would crash without a message, even though I activated the DEBUGGER option in T2D and GAIA. I had to reduce to 1 core to see the error. Eventually, I was able to trace the error to a call to CVSP_MAIN_GAIA which eventually calls CVSP_CHECK_F. The error is triggered by lines 74-76 in the latter subroutine. The error is:
CVSP_MAIN_GAIA
 CVSP CF:PRO_F>1: ERR,LT,J;K;F_I;%: check_mass           3          73          17           7   2.0125861233851587               20

It would seem that the PRO_F value is greater than 1 (output seems to be 2.01something, if I'm reading correctly), but I have no clue how to check how this value is reached. Also, this is not the first call to CVSP_MAIN_GAIA, according to the log (which I have attached).

Is this something that can be easily solved? If not, I will probably frankly give up on C-VSM for now; it would've been interesting to use in my research, but it seems that the model is not quite robust enough (yet! there is always hope) for general cases.
If it can help, I have 10 sediment classes ranging from 0.63 mm to 112 mm. They are sorted in ascending order as required by C-VSM.

Thanks so much!
