Discussion Overview
The discussion revolves around the interpolation of applied pressure from one mesh (composed of tetrahedral elements) to another mesh (composed of brick elements). Participants are exploring methods to verify the accuracy of the interpolation process.
Discussion Character
- Technical explanation
- Exploratory
- Debate/contested
Main Points Raised
- Kajal seeks advice on checks to validate the interpolation of pressure between two different mesh types.
- One participant suggests integrating the pressure over the domain as a check.
- Another proposes interpolating random points from both meshes to compare results.
- A further suggestion involves interpolating back to the original mesh to assess similarity in results.
- Kajal requests clarification on the integration of pressure and whether it involves summing pressures at nodes of each element.
- Another participant outlines a detailed procedure for checking interpolation quality, including calculating total pressure and forces on element faces for both source and destination meshes.
- There is a suggestion that if the detailed procedure is too resource-intensive, a simpler approach of checking a few points may suffice.
Areas of Agreement / Disagreement
Participants have not reached a consensus on the best method for validating the interpolation. Multiple approaches are proposed, and there is ongoing clarification and exploration of these methods.
Contextual Notes
Some participants express uncertainty regarding the integration of pressure and the specifics of the proposed checks, indicating a need for further elaboration on the methods discussed.
