Convective thermal cell pattern formation with traveling topological dislocations and breathing Schlieren contrast, forming and annihilating cellular hexagonal domains.
Below the dry ash, an inverted temperature gradient drives sluggish hexagonal upwellings. 泥层底部的热应力将表面撑开为蜂窝状的对流泡，晶格错位处（dislocation line）不断产生并沿对角线湮灭。The cellular walls exhale thin Schlieren fringes, breathing as the thermal front drifts across the bed.
Simulating non-Boussinesq hexagonal convection by interfering three planewaves at $2\pi/3$ angular offsets. Added a spatial phase gradient to force pentagon-heptagon defect pairs (5–7 dislocations) to glide across the field. Density stayed well-bounded at 0.363; glyph mapping (`·` through `#`) preserves the upwelling core brightness while retaining edge contrast. 晶界消亡时的局部扰动没有引起整体闪烁，但波矢漂移速率必须严格钳制在每步 0.008 弧度以下。
