Fatal Python error: Segmentation fault #129
Description
I tried to run the below code in ubuntu. but getting below error. Your help greatly appreciated.
import welleng as we
from tabulate import tabulate
construct simple well paths
print("Constructing wells...")
connector_reference = we.survey.from_connections(
we.connector.Connector(
pos1=[0., 0., 0.],
inc1=0.,
azi1=0.,
pos2=[-100., 0., 2000.],
inc2=90,
azi2=60,
),
step=50
)
connector_offset = we.survey.from_connections(
we.connector.Connector(
pos1=[0., 0., 0.],
inc1=0.,
azi1=225.,
pos2=[-280., -600., 2000.],
inc2=90.,
azi2=270.,
),
step=50
)
make survey objects and calculate the uncertainty covariances
print("Making surveys...")
sh_reference = we.survey.SurveyHeader(
name="reference",
azi_reference="grid"

survey_reference = we.survey.Survey(
md=connector_reference.md,

generate mesh objects of the well paths
print("Generating well meshes...")
mesh_reference = we.mesh.WellMesh(
survey_reference

mesh_offset = we.mesh.WellMesh(
survey_offset
)
determine clearances
print("Setting up clearance models...")
c = we.clearance.Clearance(

print("Calculating ISCWSA clearance...")
clearance_ISCWSA = we.clearance.ISCWSA(c)
print("Calculating mesh clearance...")
clearance_mesh = we.clearance.MeshClearance(c, sigma=2.445)
tabulate the Separation Factor results and print them
results = [
[md, sf0, sf1]
for md, sf0, sf1
in zip(c.reference.md, clearance_ISCWSA.SF, clearance_mesh.SF)

print("RESULTS\n-------")
print(tabulate(results, headers=['md', 'SF_ISCWSA', 'SF_MESH']))
get closest lines between wells
lines = we.visual.get_lines(clearance_mesh)
plot the result
we.visual.plot(
[mesh_reference.mesh, mesh_offset.mesh], # list of meshes
names=['reference', 'offset'], # list of names
colors=['red', 'blue'], # list of colors
lines=lines
)
print("Done!")
