Error when restarting - ReynoldsStresses

I'm receiving an error (not specified) when restarting a 3D simulation which has the ReynoldsStresses filter activated. I don't get the error when the simulation is 2D nor when I use the AverageFields filter. So it just happens when I use the ReynoldsStresses filter in the Quasi-3D simulation. I'm also solving a scalar equation. Would it be a bug in this specific setup condition? I tried versions 5.4 and 5.5. Or does anyone know a workaround? I'm doing separated averages to combine later with the respective FieldConvert module for now. Thank you very much, Daniel.
Hi Daniel, You could be running out of memory as you are loading files in serial and therefore reading in (u,v,wp)-average along with 9x double value components, the mesh and the instantaneous solution. You can try to convert the inst. and t-avg to HDF5 (section 5.3 in manual or ctrl-f "HDF5"), but it will also depend on the hardware you have available and whether you have installed Nektar++ with HDF5.

Hey Gugliermo, Thanks for your answer, I'll try the approach with HDF5, thank you. Em qui., 24 de out. de 2024 às 14:18, Vivarelli, Guglielmo A < guglielmo.vivarelli12@imperial.ac.uk> escreveu:
