Hi.

This is the result of all the trial and error I went through with Claude. I’m posting this in the hope that it might be helpful. There may be some inaccuracies, so please forgive me if that’s the case.

Additional Bug Report: Blender crashes when clicking "Generate"
in FloVi NetGen node on Windows 11

Environment:
- OS: Windows 11
- Blender: 4.4.3
- VI-Suite: 07 beta8
- Docker Desktop: v4.65.0
- Docker image: dicehub/openfoam:12

Problem:
Blender crashes immediately when clicking the "Generate" button
in the FloVi NetGen node.

Crash location (from crash log):
The crash occurs in the Netgen mesh saving process:

Stack trace:
  MSVCP140.dll   : Thrd_yield
  ngcore.dll     : ngcore::NgProfiler::CreateTimer
  nglib.dll      : netgen::Mesh::Save
  nglib.dll      : netgen::Mesh::Save
  nglib.dll      : ngcore::PyArchive<ngcore::BinaryOutArchive>::~PyArchive
  nglib.dll      : netgen::NetgenGeometry::Save

Error:
  ExceptionCode : EXCEPTION_ACCESS_VIOLATION
  Module        : MSVCP140.dll

The crash appears to be a compatibility issue between the Netgen
library and Blender 4.4.3 on Windows 11.

Node setup at time of crash:
  FloVi Case → FloVi NetGen → FloVi Boundary → FloVi Simulation

The geometry healing process completes successfully before the crash:
  Solids : 1
  Faces  : 40
  Edges  : 115

I would appreciate any guidance on how to resolve this issue.

Best regards,
