Comment out traces of blocks and variable names
Please stop explicitly setting the loading of blocks and variables in a trace. As blocks and variables are loaded by default, this is not necessary. Further, it makes the trace significantly more restricted. Here is the discourse discussion: https://discourse.paraview.org/t/explicitly-naming-variables-and-blocks-in-trace/8515.
So, for the trace of the load of can.exo, change
canex2 = IOSSReader(registrationName='can.ex2', FileName=['/Applications/PV/can.ex2'])
canex2.ElementBlocks = ['block_1', 'block_2']
canex2.NodeBlockFields = ['accl', 'displ', 'vel']
canex2.ElementBlockFields = ['eqps']
to
canex2 = IOSSReader(registrationName='can.ex2', FileName=['/Applications/PV/can.ex2'])
# canex2.ElementBlocks = ['block_1', 'block_2']
# canex2.NodeBlockFields = ['accl', 'displ', 'vel']
# canex2.ElementBlockFields = ['eqps']
