[Silvaco] maybe easy error about grid points

[Jose Bartra]

Hello, I'm suffering continuous error about setting grid points
the error code is like that
ATLAS> mesh infile=ath_bjt.str

Error: Error in mesh definition.
Insufficient number of grid points.

And my code about making npn BJT with Athena simulation is down there

go athena

line x loc=0 spac=0.15
line x loc=0.8 spac=0.01
line x loc=1.5 spac=0.01
line x loc=2 spac=0.15

line y loc=0 spac=0.01
line y loc=0.5 spac=0.01
line y loc=1 spac=0.15

save outf=ath_bjt.str

go atlas

mesh infile=ath_bjt.str

electrode name=E x.min=0, x.max=0.8, y.min=0
electrode name=B x.min=0.8, x.max=1.5, y.min=0
electrode name=C x.min=1.5, x.max=2, y.min=0

models ath_bjt

#code about setting different base voltage
structure outfile=ath_bjt_structure.str

tonyplot -overlay.log .log ~~
quit

my major goal for this code is comparing Ic-Vbe curve with other given base Voltage
and GPT-4 said there's no problem on this code
