EFFICIENT COMPUTATION OF MAGNETO-HYDRODYNAMIC PHENOMENA IN ASTROPHYSICS BY CCUP-MOCCT METHOD
Bibliographic record
Abstract
We proved that the CIP (Constrained Interpolation Profile/Cubic Interpolated Pseudoparticle)-MOCCT (Method of Characteristics/Constrained Transport) is capable of treating MHD phenomena using a mesh several times coarser than the conventional schemes. Comparing the present method with the modified Lax-Wendroff methods in the Parker instability in two and three dimensions, the superiority of the CIP scheme has been demonstrated from its low numerical phase error and damping rate. In addition, we employ the CIP-CUP (CIP-combined unified procedure/CCUP) method that solves the Poisson equation for pressure in order to make the present scheme more stable. This method is able to treat the pressure scale height having just one grid, which is five times coarser than the conventional scheme, as well as the magnetic reconnection, which has been described with a coarse grid.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
