The leakoff rate becomes positive in the middle range of the crack

[neclipse]

Description:

• At the injeciton point, the leakoff rate is definitely negative, and close to the injection rate.
• Near the tip, the leakoff is also negative, and a small value.
• In the middle range, the leakoff rate becomes positive (to the formation.)

Analysis: is this all right?

This is the all-time pain in my debugging: the leak-off is always higher than expected.
