Fatal error: Invalid setNodes (ob)

[MZecchini]

Dear ES3 staff,

I tried to run a simulation of an LDPM concrete block with some steel reinforcements inside using an old MARS version (2018-03-15).
Unfortunately, during the initialization of the Paraview List which should plot the concrete cracks, I get the error: 'Fatal Error - Invalid setNodes (ob). Notify ES3"

At the same time, using the latest Mars version does not create the crack Paraview files even if I don't get the same error.

Did I miss something in my Run file?

Thanks for the support.
Best,
Michele
