Summary0015199: EnSightReader: Change input file
DescriptionSubject: [Paraview] EnSightReader: Change input file
------------------------

Hi all,

I want to apply the same pipeline to a series of Ensight data files in order to save extractions in a different format. For the first file, this works fine. For the second file, I thought I could change the input file by changing the CaseFileName attribute:

reader.CaseFileName = nextfile

But when I run

reader.UpdatePipeline()

I get a segmentation fault. This depends neither on the file, nor on the pipeline following.

I tried a workaround by building up a new pipeline for each file. It works, and as I have only two files by now, it is ok to do that, but for more files, memory usage would explode. Therefore, my question is: Is it possible only to change the input file of the EnSightReader, while keeping the pipeline?

Kind regards
Ian

Ability to change filenames depends on specific reader
implementations. I am not entire familiar with the internal
implementation, but if you have a couple of sample datasets/script to
reproduce the segfault, I can check if its a minor fix to the reader
to enable this or if it just can't support it.

Either case, you should be able to call Delete(reader) to delete old
reader once you're done with it to avoid memory bloat.

Ok, the problem obviously does depend on the input files to a certain degree. I use TAU as a flow solver (from the DLR, Germany), and it gives me two solution files, one for the fluid solution, one for the surface data. The problem with the EnSightReader occurs, when I try to switch from one category to the other (no matter, which direction). However, there is no problem loading another file of the same category, even with another geometry.

I attach two solution file sets, fluid and surface, with a short pvpython script to reproduce the error (sorry, that they are not smaller, but I do not create any grids of my own).
The behaviour is the same with ParaView versions 3.14.1 and 4.2.0.

Kind regards
Ian

 If I understand the problem correctly, I just tested it and it doesn't crash. Tested with the (excellent) attached test.

Tested Linux, master, local server. Used Tools/ Python Shell.
