Hi Michael, Thanks for your response. That is possible since I have 6 million nodes and 4 million elements. However, I was able to open a file with 1 million nodes and 7 million elements before...
And I have this new file that's 30k nodes long and 600k elements. It just crashed paraview (quit unexpectedly is the message I got from the Mac OS) without giving any sort of warning. Did that three times... What could this problem here? (I checked the number of elements, nodes etc and everything seems legit and it's way smaller than what I was able to open...)
