Re: [sumo-user] Error with electric hybrid and overhead wires
|
Dear Rehab,
this is due to two things:
- the default value for --overhead-wire.solver is true
- in that case the energy computation will make use of the external Eigen library (a fallback solution for --overhead-wire.solver false is provided)
What does not work is activating the solver when you don't have the library for it. Many external libraries with differing licenses have been packaged into a separate "extra" release. When you build SUMO yourself, you have to make sure they have been found. If you download precompiled Windows binaries, be sure to choose the "extra" version.
Best regards
Mirko

Hi all,
I was doing some experiments using the electric hybrid and overhead wires.
I tried the test scenario in: $SUMO_HOME\tests\sumo\devices\elechybrid\elechybrid_2 but
I'm getting weird behavior. First, I received the following runtime error when I ran the scenario using SUMO gui (but the simulation runs successfully and I can see the wires changing colors)
Error: Overhead wire solver is on, but the Eigen library has not been compiled in!
and the simulation output files (the traction substation output, overhead wires output) indicates that energy charged is always 0, although the pre-generated output that comes with the test indicates non zero values for the mentioned output files.
Am I missing something? I am using version 1.19.0
Thanks,
Rehab
