Support I,J,K-based definition of fault segment orientation

[olwijn]

Item 8 of each record under the Eclipse keyword FAULTS indicates the orientation of the face of a fault segment. This should be one of X, Y, Z or I, J, K. FlowNet currently only supports X, Y, Z. The I, J, K orientation is used in the current field case. The script _from_flow.py should be modifed as follows:

if row["FACE"] == "X" or row["FACE"] == "X+" or row["FACE"] == "I" or row["FACE"] == "I+":
points.append((row["NAME"], i + 1, j, k))
elif row["FACE"] == "Y" or row["FACE"] == "Y+" or row["FACE"] == "J" or row["FACE"] == "J+":
points.append((row["NAME"], i, j + 1, k))
elif row["FACE"] == "Z" or row["FACE"] == "Z+" or row["FACE"] == "K" or row["FACE"] == "K+":
points.append((row["NAME"], i, j, k + 1))
elif row["FACE"] == "X-" or row["FACE"] == "I-":
points.append((row["NAME"], i - 1, j, k))
elif row["FACE"] == "Y-" or row["FACE"] == "J-":
points.append((row["NAME"], i, j - 1, k))
elif row["FACE"] == "Z-" or row["FACE"] == "K-":
points.append((row["NAME"], i, j, k - 1))
else:
raise ValueError(
f"Could not interpret '{row['FACE']}' while reading the FAULTS keyword."
