A method, performed by a data-processing system, of simulating fluid transport in a system for stimulating a well in a material formation, which system comprises a limited entry liner, LEL,, wherein the liner is divided into segments, each of which having a length less than that of the total length of the liner, and which includes one or more holes along a wall of the liner for discharging a fluid into the formation, characterized in that the method provides an initial estimate of the number of holes along the wall of the liner which honours the acid coverage per segment and the drop in pressure across the last hole, for an optimized hole-size distribution in construction and operation of the system, adjusting the initial estimate of the number of holes along the wall of the liner if the acid coverage per segment and the drop in pressure across the last hole is not honoured; and wherein the method further comprises: performing a series of algebraic equations for an initial hole-size distribution guess; calculating acid coverage and dp across the last hole; comparing acid coverage and dp across the last hole against a design variable in a first iteration; evenly decreasing the number of holes across a segment for a next iteration until dp across the last hole is honoured; or evenly increasing the number of holes across a segment for a next iteration until dp across the last hole is honoured, as a first step; and performing a second step which includes: redistributing existing number of holes between various segments as a first iteration, wherein segments, where the calculated acid coverage is the furthest away from design values, exchange one hole; performing the next iteration until acid coverage is honoured; and performing the first step and the second step until dp across the last hole and acid coverage is honoured; and wherein the method further comprises: operating the system for stimulating the well in the material formation using the optimized hole-size distribution. the method provides an initial estimate of the number of holes along the wall of the liner which honours the acid coverage per segment and the drop in pressure across the last hole, for an optimized hole-size distribution in construction and operation of the system, adjusting the initial estimate of the number of holes along the wall of the liner if the acid coverage per segment and the drop in pressure across the last hole is not honoured;
