why this convergence error happens?

#1
Hello,

I want to use HYDRUS1D with UNSATCHEM module to simulate the sodic soil development under shallow sodic-quality groundwater environment. The relevant input parameters are based on the existed lituratures (see the attached HYDRUS-1D documents for detail). I plan to run the model for 20 years. Firstly, I run the model with loam soil type and it can successfully run for 20 years. However, when I change the soil type from loam to silt loam, the model was stopped at around 3400 days due to convergence error. Could you give me some suggestions on why this convergence error happens? Or some suggestions on adjusting input parameters to avoid such convergence error?

Please help.

I didn't find the right solution from the internet.
