SUMMARY

The forum discussion centers around the "geometry error in newcel" encountered while using MCNP (Monte Carlo N-Particle Transport Code). Users reported that the error occurs when a point source is placed near the interface of two cells, leading to a halted run and no output file. One participant successfully resolved the issue by adjusting the input file, indicating that proper placement of the point source is crucial for successful execution.

PREREQUISITES
  • Familiarity with MCNP (Monte Carlo N-Particle Transport Code)
  • Understanding of geometry setup in MCNP simulations
  • Knowledge of point source placement in computational models
  • Experience with input file configuration for MCNP runs
NEXT STEPS
  • Review MCNP documentation on geometry errors and troubleshooting
  • Learn best practices for point source placement in MCNP
  • Explore techniques for validating input files before running simulations
  • Investigate common issues and resolutions in MCNP user forums
USEFUL FOR

Researchers, physicists, and engineers working with MCNP simulations, particularly those dealing with geometry configurations and troubleshooting simulation errors.

Hello everyone,

trying a run I've got the following error message, and thus no output file since the run stopped by itsefl.
Please, has anyone encountered this error and would happen to know how to correct the input file ? (any hint help)

Thanks to all of you

Hi,
like in the french forum (private joke) it is a geometry error,

Hi,
thanks to you, I found the error
 
i encountered this error too but i got ouput... i put the point source near the interface of two cells and the error arises
