Hello, Thank you for your answer.
Obviously, replacing the invalid data by some number seems to be the only way. After digging through the Paraview-source I found, that the vtk-files are read using an istream object with the >> operator ( http://www.cplusplus.com/reference/iostream/istream/operator%3E%3E/ ), that by standardization does not support non-number-arguments. So I changed my converter script to replace any "NaN" by something like -0.9999E30. The value -1e99 did not work for me. Obviously, the allowed data range is limited to exponents somewhere around 1e43. However, I did not check that in detail... If anybody has a better solution, pleas let me know :-) Thank you and have a nice weekend, Mathias Oliver Gloth wrote: > Hi, > > what about -1e99, that's what I have done so far.
