Hi all.

I am trying to calibrate a 3D unconfined aquifer system using FEPEST and found that the model ended with error message below:

'[ERROR] Missing matrix column: 400|27440.98^7807.29^10.00^-1'

Can anyone explain what sort of problem my model has and how I can fix it?

Thank you in advance. 

Thanks. It's pretty useful advice and I'll check the manual!

Hello.
I have questions about the error bound of my simulaion results.
It is a fully hypothetical model and have no data to compare with. In that case, how can I decide the error bound of my model?
If it is relevant to the numerical scheme, how can I obtain the error ranges when using the default setting of FEFLOW?
Please, I need you guys' help. It would be very greatful to recommend any refernces on it.
