Initial Value Problem setting

Post by thotran11292 » Thu Aug 08, 2024 5:45 am

Dear all,

I am using the CXTFIT model to simulate a soil column where the top 5 cm layer is initially contaminated with arsenic. Free-arsenic water continuously infiltrates through the soil column from the top. I want to observe how the arsenic concentration changes over time at a depth of 100 cm in the column. I am struggling with setting the initial value problem in the model and am unsure which option to select from the given choices.

I am looking forward to your suggestions and explanations.

Thank you

Tho Tran
