Discussion Overview
The discussion centers around the use of IMESH, JMESH, and KMESH values in the context of FMESH in MCNP, particularly addressing a specific error message regarding the "imesh keyword missing." Participants seek clarification on the definitions and applications of these mesh values, as well as troubleshooting advice for coding issues related to FMESH syntax.
Discussion Character
- Technical explanation
- Homework-related
- Debate/contested
Main Points Raised
- One participant requests clarification on the definitions of IMESH, JMESH, and KMESH values, expressing confusion over the term "coarse mesh points" as described in the MCNP manual.
- Another participant explains that IMESH can be used to specify large divisions (coarse divisions) and that IINTS can further divide these into smaller divisions, providing an example of how to structure the FMESH card.
- A different participant suggests that the error "imesh keyword missing" may be due to insufficient spacing in the FMESH card syntax.
- One participant inquires about the correct syntax for multipliers in their code and asks if there is any FM syntax for power density that can be used with FMESH.
Areas of Agreement / Disagreement
Participants express varying levels of understanding regarding the definitions and applications of IMESH, JMESH, and KMESH, with some providing explanations while others remain confused. The discussion includes troubleshooting advice but does not reach a consensus on the cause of the "imesh keyword missing" error.
Contextual Notes
There are indications of missing assumptions regarding the formatting of the FMESH card and the specific requirements for IMESH, JMESH, and KMESH values. The discussion does not resolve these uncertainties.
