[Paraview] FW: Paraview

[Moreland, Kenneth]

Specifically, what filename did you give to the CreateWriter function?
Did you give "myFile.csv" as in your example?  If so, try a full path as
Utkarsh accepted.  Did you give "/myFile.csv", and if so, do you have
write access to your root directory?  Did you give something like
"/tmp/myFile.csv" and it still tried to write to "/myFile.0.csv"?
