Hi,

I try to open my vtu file in Open SUSE. Ryzen 5800X / 64GB / GTX1080
My vtu file is quite large(>5GB) and has many nodes (~ 1e7).
When I open it and try to check my data graphically, it makes my computer too slow.

So, is there any technique to check or control large file?
I want to throw out some of my data or change sampling resolution.

Thank you in advance.

Memory Wise, you can’t do anything.
To graphically make the interaction faster you can try to adjust the LOD Threshold value in Edit->Settings->RenderView. The lower the LOD Threshold the smoother the rotations will be.

You can downsample your data or even sample around a region of interest and disregard the rest using ResampleToImage
