- CoolSim 5.4.180 preview 12
An opt-in early build of the CoolSim desktop app: the Room Editor no longer lifts turning-vane cooling units, a typed air density reaches the solver, Frontflow PDUs stand on a solid floor, cable cutouts stay inside the room, and Run Simulation warns before a run would drop CRAC Parameter Variation. It carries every fix of earlier previews, including CRAC Parameter Variation on CoolSim’s new simulation service once your account moves there. It installs beside your current CoolSim, and comes in CoolSim 5.4’s classic look too.
