ENVI-met PLUGIN: SIMULATION PROBLEM

Good evening,
I am trying to run a simulation with the ENVI-met plugin but I am having a few problems that I can’t figure out. I am new to Grasshoper and ENVI-met so the solutions to my questions might be very simple…

  1. In order to see the grid on my buildings I am using the ENVI-met Facade but the grid doesn’t appear.
  2. I am running my simulation straight from grasshoper. It looks like the simulation is finished but then there are no output files in the output folder.

Any help with these two problems would be greatly appreciated!
Thanks!
