IDF data is not supported by SWMM solver. The IDF storm event was not exported.

I am running the model with Implicit SWMM solver (Modified Rational Method) using IDF data, flows are getting generated but it shows the error "IDF data is not supported by SWMM solver. The IDF storm event was not exported."

  • Yes the results are valid and can be used for further analysis.

    This user notification lets you know that if you were to export model to EPA-SWMM, then you may need to change the global storm event and storm event will not be exported for current method into INP file. 

    The message is just informational that the IDF storm data was not included in the SWMM INP file that gets created during the process of computing with the SWMM solver.
