RSICC CODE PACKAGE PSR-618
1. NAME AND TITLE
Schwarz Software & Consulting, Richland, Washington, USA
3. CODING LANGUAGE AND COMPUTER
C++, Windows. (P00618PCX8600).
4. NATURE OF PROBLEM SOLVED
Visplot61_25 is a program that can plot and run Monte Carlo N-particle© (MCNP©) calculations. Display capabilities include geometry plotting, tally plotting including mesh tallies (both TMESH and FMESH) and weight windows. More advanced plotting features include the plotting of particle collision points, 3D dynamic geometries and 3D ray traced geometries Visplot61_25 has no creation capabilities. Visplot61_25 has no creation capabilities. VisedX_25 has most of the plotting capabilities (except FMESH which is MCNP6© specific) of Visplot61_25 and also has the capability of creating general geometries using the surface and cell creations windows. Surface creation includes both general quadratic surfaces and macrobodies. The surface wizard guides users in creating any valid MCNP© surface. The user can the create cells from these surfaces using the mouse. A lattice wizard allows the user to create both rectangular and hexagonal lattices. As the geometry is visually created, the input file is generated. The input file can be run both inside the visual editor and in the MCNP® command prompt outside the Visual Editor.
5. METHOD OF SOLUTION
VisedX_25.exe is the full Visual Editor executable (creation and display) based on MCNPX 2.7.0© Visplot61_25.exe is a limited (no creation features) version of the Visual Editor that only has display capabilities. Plots that can be made in Visplot61_25 include geometry plotting, tally plotting, cross section plotting, mesh tallies plots (both TMESH and FMESH), weight window plots. More advance plots include particle track plotting, dynamic 3D display plots (using OpenGL), and 3D ray traced plots. This Visual Editor is based on MCNP6.1© Users can create geometries in VisedX_25 and then display them in Visplot61_25. If the input file contains MCNP6 features that are not part of MCNPX (i.e. FMESH), errors will be generated when loading the file in VisedX_25. Users are encouraged to visit the developer’s website to attend a workshop to learn all the many capabilities of the Visual Editor www.mcnpvised.com.
6. RESTRICTIONS OR LIMITATIONS
Users must purchase and install the MCNP6© package so the Visual Editor has access to the cross sections. Input files created in VisedX_25 can by run in MCNP 6.2©.
7. TYPICAL RUNNING TIME
The interactive running times depends upon the complexity of the input file being created.
8. COMPUTER HARDWARE REQUIREMENTS
Windows systems only.
9. COMPUTER SOFTWARE REQUIREMENTS
Users must purchase and install the MCNP package so the Visual Editor has access to the cross sections. Included in this distribution are two material files based on PNNL-15870 Rev1. (stndrd.n and stndrd.p). The Visual Editor can read these files if they are in the same directory as input file or if they are placed in a “VISED” directory that is at the same level as the MCNP_DATA directory (i.e. c:\mcnp6\vised, if you installed mcnp6© in c:\mcnp6). All versions of the Visual Editor must have access to the DATAPATH for accessing the cross sections. You can either run the Visual Editor within the MCNP6© command prompt (just type the executable name) or define the DATAPATH environment variable for your computer (computer->properties->advanced system settings->environment variables). Details on how to do this can be found on the website here: http://www.mcnpvised.com/HelpAndSupport/HelpAndSupport.
