Hello everyone
I don't know if I understood it wrong，When I open B 60 2 and provide the hydrograph.dat file,I can set inflow to change over time,The first column is a time step, and I need to set the corresponding discharge value for each time step in the second column.But when I did this, the terminal gave me the following message

ERROR detected by Hypre ... BEGIN
ERROR -- hypre_BiCGSTABSolve: INFs and/or NaNs detected in input.
User probably placed non-numerics in supplied b.
Returning error flag += 101. Program not terminated.
ERROR detected by Hypre ... END

This seems to mean that I didn't provide the values needed for the calculation correctly.I'll put my settings below, and I'd like to know the correct "hydrograph.dat" file format and how to modify it.

Can you upload your complete set of input files so that I can take a look?
