Residuals in Eddy 3D

I am running a multi-directional wind analysis for a building block, with Eddy 3D in Grasshopper and although it looks like the simulation was done I am still not able to get the residual points.
There is this error message that comes out.

Does anyone know how this can be resolved?
Thank you.

this is the error message:

  1. There is no native Gnuplot version installed, please consider selecting the version that comes with BlueCFD.

This fixed the error for me:

in “Ver” select “BlueCFD gnuplot” instead of “Windows gnuplot”
