As of version 2024.b, drain catalogues can now be entered. Previously, only one drain could be entered as a single generic discharge. Now, any type of drain from a manufacturer's catalogue can be included in the system.
The manufacturer's catalogue currently included in the program comes from Aliaxis, although users can enter their own catalogues or those of other manufacturers with the data provided by the latter.
In "Technical properties" ("General options" > "Design and check options to be carried out") users can choose the corresponding material of the drain from those defined in the library of drain catalogues.
