FEH22 Rainfall via the Exchange

Given the current workload involved in generating FEH22 rainfall data, it would be highly beneficial if this functionality could be made available through the InfoWorks ICM Exchange. This would streamline workflows and significantly reduce manual effort across projects.

    You are right Sebastian, when the design rainfall relies on external services such as (ARR and NOAA), we cannot call this through exchange. However, there is nothing stopping us from checking the licencing term of each provider and implement these synthetic storms through exchange.

    There is an ongoing conversation to do this for NOAA and ARR and I've just added FEH22 for consideration.

    I will move the status of this to "Under Consideration" since you're only interested in synthetic rainfall that relies on external providers.

    Thank you, Samer.
    I am currently working with ICM version 2026, and the rainfall type I proposed to add is FEH2022 Rainfall. According to the existing documentation in the help file, the following applies:
    "Rainfall type XXXX cannot be created by scripting. Input type must be one of the following: FEH2013, FEH2022, AUS2016Rain, NOAARain. These cannot be created using scripting because they require external software."
    In the script, the rainfall type is set as 'UKRain'. At present, generating FEH22 rainfall in ICM 2026 is still not possible, unless I am wrong, please tell me I am wrong and that its possible to generate FEH22 in 2026.

    Thank you for raising this and thanks to those who voted.

    Would you please confirm which version are you working from? We have exposed scripting API for rainfall generators to users a year ago, try any version after 2026.0 and you should be able to generate design rainfall using exchange.

    Try the attached ruby script to generate synthetic rainfall event and let me know how you get on.
