The issue with this approach is that EPANET 2 itself supports older INP formats and upon opening an INP in EPANET 2, if it detects such older file formats it does silent updates to convert the data into EPANET 2 format. Typically, software developers verify the 'correctness' of their exported format by importing a model into EPANET 2 and checking hydraulic results. Solution - EPANET (WaterCAD / WaterGEMS / HAMMER) INP format by opening it in EPANET (free download), then go to File > Export > Network. net file, you need to first export that to. This may occur in some cases where the EPANET or EPASWMM file is in an older format or if it was created from a third-party software that did not properly export the file (or exported it with non-standard formatting). For example, all the junctions in the model file are at a 0, 0 location.ĥ) The program crashes with a dialog titled 'Assertion Failed'Ħ) Missing pipes when exporting to EPANET (see 'see also' below) Background INP file (EPANET) the model doesn't display correctly.

Error message: The specified EPANET file contains values with no section.
