Hello Ghulam,

I built a small model based on the data you sent. I added a line to the
data points with an END. If this is not in the trp file, feflow will
not read the file. I used the file to Assign/Database/Data
Regionalization menu to assign initial heads. It worked fine.

Is it possible that the coordinate system of your fem is different from
the coordinate system in your trp file? If the points in the trp are
outside the fem due to a difference in coordinate systems, it cannot
find any points inside the model to work with resulting in the error
message you see.
