Unable to read file to Meshalyzer

Question

I was trying to open some 3d meshes from this paper (https://zenodo.org/record/3890034#.Y197rOzMKWh) using meshalyzer, however, even though it did not show any error messages, it only displays blank when I open them. I have tried both the original vtk version and the converted pts ones from meshtools.

Please let me know if you have some ideas on how to solve this issue. Thank you.

Answer 1

These are massive meshes. On my machine ParaView also struggles with displaying them. You might want to downsample them (e.g. using meshtool resample) or to extract a smaller submesh for visualization.

What size would be small enough?

Been trying to use meshtool resample, but always get this error:
Resampling op 1/1: Processing tags: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24
terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc

Answer 2

Hi,

You need to compute the surfaces of the mesh with meshalyzer. To do so, one the pts file with meshalyzer and you will get the white screen. Go to the menu and in files you have the option compute surfaces. Click on compute surfaces and a window will appear click ok and the mesh should appear.

Cheers,
