After importing the ‘inp’ file, only 2 junctions show up with one pipe connecting them. At the same time it appears that every junction and pipe are there when looking at the browser window. If I try to zoom out or do anything on screen it gives a warning that says “Floating point overflow”. Can anyone help?

For those who have the problem “ERROR: Illegal numerical value in DXF file”, try to change the Regional Preferences in Control Panel. Change the decimal separator to . instead of , and the number separation for a space instead of . or ,

I made this change and it worked.

Other thing is to use the Epanet in English instead of other languages (I was using Portuguese version and now I am using the English version).

If someone knows how to create the inp file with the elevations of the junctions please let me know. This program doesn’t permit this option, according to the specifications (I tried to find other aplication but I was unsuccessful)

I have been successful importing the dwf file into EPANET, but am curious if there is an easy way to combine .inp files. In EPANET, after one is imported, if I import another it deletes the original information. I have a large network with many pipe diameters and would like to create separate .inp files for each pipe diameter, but import them into one model. Then I can group edit each import to update the pipe diameter. Any suggestions?

Ya he descubierto la soluciֳ³n al mensaje: “ERROR: Illegal numerical value in DXF file.”.

El autocad genera el dxf con puntos decimales “.” y la configuracion regional de windows debe ser tambien asֳ, para que el EPANET entienda los decimales.
