Picture the scene\u2026 The news channels had been reporting the disappearance of Simon Cary from the All Hallows Asylum for over a week now. Tom pretended, more to himself than anyone else, that there was no need for concern. Tom had been doing things as usual since the story broke, waking up, going to work, going through the motions. The fleeting glimpse he had yesterday during his lunch break had begun to unsettle him though. It could have been anyone, it might have been anyone, surely it couldn\u2019t have been Simon. <\/p>\n\n\n\n

22 years is a long time, long enough to obscure, to bury, the most traumatic of childhood memories. Out of the group of them, Chris, Peter, Vincent and Tom, it wasn\u2019t as if Tom was the ring leader, the main instigator of what happened. 10 year olds might be spiteful on occasion, especially in a group, but Tom didn\u2019t consider himself solely responsible. Not the Tom of today, mortgaged, married and so very different, so very not that 10 year old. It was meant to be fun, a Halloween prank, they couldn\u2019t have realized how Simon would have reacted, he didn\u2019t have to turn around, he didn\u2019t have to look behind him. <\/p>\n\n\n\n

It was the shadow right at the bottom of the yard Tom saw this evening, out of the window, in the fading dusk, that really began to set him on edge. Partly obscured by the overgrown bushes he\u2019d been meaning to attend to for ages, might have been nothing, but it was tall, kind of hunched and almost moving, then it was gone, not there. Call the police? And tell them what? Forget it. Get on, ignore it, grow up, grow up, don\u2019t ever be 10 again. But still his memories dragged him back to that night.<\/p>\n\n\n\n

It hadn\u2019t taken much to organise, a trip to the butchers, some string, some paint, a little imagination. The bravado of 10 year olds, giggling all the while. They\u2019d set it up by the lopsided tree just outside old Macintosh\u2019s yard up on Elm. It also hadn\u2019t taken much to get Simon to join them, ever eager, ever smiling, ever willing to make friends. \u201cCome on Si, a bit further, no seriously, you\u2019ve got to see this! There, over there, just behind you, look behind you, LOOK!\u201d and he did. It happened suddenly after he turned, no one expected it, how could we? We were only 10, why did he have to look? It happened so quickly, so suddenly. Simon crumpled, shaking, screaming, and we all ran.<\/p>\n\n\n\n

Flashing lights, interviews in badly lit rooms, mum and dad embarrassed to the point of silence, memories so fogged, so forgotten. As for Peter\u2019s parents, they left the next week, never came back, sold up. Started afresh up in Castle Rock. Tom didn\u2019t see much of Vincent and Chris after that either, moved to separate schools, separated. Then it all faded quickly, returning to some semblance of adjusted normality. Growing up and then it forgotten. <\/p>\n\n\n\n

Tom sighed and went up to bed. He hadn\u2019t heard the rear door open, slowly, quietly, shadow passing up the stairs. Quick shave and to bed. Mirror steaming up as the hot water gushes out to fill the sink. <\/p>\n\n\n\n

Wait, what\u2019s that say\u2026<\/h2>\n\n\n\n

Back to reality\u2026. <\/h2>\n\n\n\n

The fogging mirror was simulated with Simcenter FLOEFD using its \u2018water film\u2019 capability. The animation shows water film thickness on the surface of the mirror as white if the water film is > 0.3 microns thick. The original mirror is dark grey, simulation starts at time = 0 s with the mirror having no condensation on it but situated in a high humidity environment. Over time the humid air condenses on the cold mirror. CAD faces can be set to be non-wettable in Simcenter FLOEFD, i.e. will not experience any condensation on them, much like if you mark out with a soapy finger some invisible words beforehand, as \u2018Simon\u2019 had done. Good life hack if you ever need to shave in a mirror in a shower room! The film simulation even predicts the dropping down of the water film due to gravity. <\/p>\n\n\n\n

Simcenter FLOEFD has seen marked success when applied to automotive lighting applications, especially LED based solutions. LEDs run cold, compared to other lighting solutions, and so with a much cooler housing the risk of lens condensation, fogging and subsequent lighting safety concerns is much increased. The highly complex geometries coupled with Simcenter FLOEFD’s Octree meshing approach, a specialized sub grid boundary layer resolution method and an LED simulation module make Simcenter FLOEFD the perfect choice for such CFD\/Thermal\/Optical lighting applications, as seen in the following animation. The lamp cluster heats up, due primarily to optical radiative effects, and reduces the initial water film thickness due to evaporation over time. <\/p>\n\n\n\n
