Prevention Tips

Check injection locations, runner/runnerless setups, vents, and pack/hold settings for correctness.
Reduce extremes: lower injection speed/pressure, increase melt/cool times, or relax convergence tolerances for testing.
Temporarily turn off advanced features (e.g., fiber orientation coupling) to isolate the cause.
