Here's a funny issue with an Exodus file (test.e). It contains two triangles, four nodes, and on the four nodes two data points a and b. The data can be read with, e.g.,

import netCDF4

nc = netCDF4.Dataset("test.e")

names = nc.variables["name_nod_var"]
names.set_auto_mask(False)
point_data_names = [b"".join(c).decode("UTF-8") for c in names[:]]
print(point_data_names)

value1 = nc.variables["vals_nod_var1"]
value1.set_auto_mask(False)
print(value1[:])

value2 = nc.variables["vals_nod_var2"]
value2.set_auto_mask(False)
print(value2[:])

Output:

['a', 'b']
[[0.5488135  0.71518937 0.60276338 0.54488318]]
[[0.4236548  0.64589411 0.43758721 0.891773  ]]

Looks good. Now, when opening the file with ParaView, the node coordinates and the connectivity are read alright, but the data is off:

Is this a ParaView bug?
