1. A heater assembly for an aerosol-generating system, the heater assembly comprising:
a fluid-permeable heating element configured to vaporise a liquid aerosol-forming substrate; and
a transport material configured to transport liquid aerosol-forming substrate to the fluid-permeable heating element, the transport material having a thickness defined between a first surface of the transport material and an opposing second surface of the transport material,
wherein the first surface is arranged in fluid communication with the fluid-permeable heating element and the second surface is arranged to receive liquid aerosol-forming substrate,
wherein the second surface of the transport material is provided with at least one hole that extends into the transport material to a depth corresponding to at least a part of the thickness of the transport material to define a formed fluid channel for the liquid aerosol-forming substrate, and
wherein the first surface of the transport material is convex.
