I'm analyzing the sensitivity of 19 parameters using the Sobol method in version 3.1.0. When I set seed = 500 (which I believe generates around 20,000 samples), the SWAT+ Toolbox unexpectedly closes after a few hours. Has anyone experienced this issue or knows what might be causing it? Also, is there an ideal seed value or sample size recommendation for this kind of analysis?


Thank you

Samples should be around 1500. 20,000 is excessive, probably your computer runs out of memory. If you want me to try tunning sensitivity analysis, please send me your .sptp file which you can get by exporting project (not spt zippied folder)
