Dear Sir,
If i install pumping well in my model, input pumping rate should be negative values right ? and positive values for recharge ?

Could anyone explain me ?

This is copied from the manual:
Q(n) - Prescribed recharge/discharge rate at node n; [L^2T^-1] for planar flow, [L^3T^-1] for axisymmetric flow. Q(n) is negative when directed out of the system. When no value for Q(n) is needed, set Q(n) equal to zero.
