Initialize hangs in pyDEME after setup on WSL Ubuntu 22.04 (CUDA 12.8, Blackwell) #70

Description

@sunho75

Summary

pyDEME installs successfully and imports correctly, but execution stalls during Initialize().

Environment

  • Host OS: Windows
  • Linux: WSL2 Ubuntu 22.04
  • GPU: NVIDIA RTX PRO 5000 Blackwell
  • Driver (WSL-visible): NVIDIA-SMI reports CUDA Version 13.2
  • CUDA toolkit used for run: 12.8 (/usr/local/cuda-12.8)
  • Python: 3.11 (conda env)
  • Package: DEME==2.3.3 (pip install)

What works

  • pip install DEME succeeds
  • import DEME succeeds
  • DEMSolver() creation succeeds
  • Scene/material setup succeeds

Minimal repro behavior

A minimal script with markers shows:

  • P0_START
  • P1_SOLVER
  • P2_SETUP
  • then no further progress inside Initialize()

Console output (last lines):
