SUMMARY

Drawing complex geometries in MCNP (Monte Carlo N-Particle Transport Code) is primarily achieved by importing CAD drawings into the MCNP Visual Editor. Users seeking to create intricate geometrical shapes must utilize this method, as direct drawing within MCNP is limited. Tutorials and resources for importing CAD files into the Visual Editor are essential for effective geometry creation. The discussion emphasizes the importance of understanding the import process to enhance modeling capabilities in MCNP.

PREREQUISITES
  • Familiarity with MCNP 6.2 and its Visual Editor
  • Basic understanding of CAD software for geometry design
  • Knowledge of file formats compatible with MCNP for import
  • Experience with Monte Carlo simulations in radiation transport
NEXT STEPS
  • Research how to import CAD files into MCNP Visual Editor
  • Explore tutorials on creating geometries in MCNP 6.2
  • Learn about compatible CAD file formats for MCNP
  • Investigate advanced geometry modeling techniques in MCNP
USEFUL FOR

MCNP users, radiation physicists, and engineers involved in complex geometry modeling and simulation in radiation transport applications.

How does it possible to draw complex geometry in Mcnp?. If the only solution is to import cad drawing into visual editor in this case, please explain, is there any tutorial link to do it . Thanks is advance

A year old post. Probably not going to be useful to respond, but in case.

There are some projects to import CAD drawings to MCNP, but they seem to have gotten lost. The latest version of MCNP supposedly has some CAD ability but I cannot report directly. My last use of MCNP was 6.1. If you Google for it you might get lucky, but I would not bet the farm.

Most likely you will be stuck typing it in by hand. Or possibly writing some relatively simple scripts to produce repeating parts of your system like fuel pins that are copied across a core. Or sometimes you will get lucky and be able to copy-paste some parts of your system.

MCNP comes with a utility called VisEd. You can use this to preview your model. It's frustrating because it has limits on how complicated the model can be. If your model gets complicated you will probably first be limited to the 2-D view, and then a little more complicated and it won't work at all. And giving VisEd a model with a bug in it can easily cause VisEd to crash and leave files behind you have to delete by hand to get it to run again.

If you have MCNP set up on a system with a good X-Windows emulator, you should be able to run the plotter that is built into MCNP. This is only 2-D, but is very helpful. Read up in the manual about that.
