Specify cylindrical in the mesh statement for Atlas. (The following is fron one of Silvaco's examples)

#
mesh rect smooth=1 diag.flip cylindrical
x.m l=0.0 spac=20
x.m l=80.0 spac=10
x.m l=200.0 spac=50
#
y.m l=0.0 spac=1.0
y.m l=3.2 spac=0.1
y.m l=5.0 spac=0.5
y.m l=7.0 spac=0.1
y.m l=15.0 spac=3.0
#

SEGV means an internal program has crashed.
