CoolSim Post Processing Overview

beginner
A tour of CoolSim version 5 results: email notices, report tables, 3D plots, custom cut planes, post-only reruns and hyperlinked sharing.

This video gives an overview of the output and post-processing tools in CoolSim version 5. It walks through a solved raised-floor model and then shows how to change the plots without re-solving.

What the video shows

  1. Plot setup: the base report needs no changes, and the job processes after submission.
  2. Email notices: a start email, then a completion email with the start and stop times and a PDF report attached. The example run took about half an hour.
  3. The report tab: the Status button shows progress or opens the finished report. The numerical data covers the room description, an energy report with the Return Temperature Index (RTI) and Rack Cooling Index (RCI), the rack cooling report (minimum, maximum and average inlet temperatures against the ASHRAE recommended range), the vent tile report with each tile’s deviation from the mean, and the computer room air conditioner (CRAC) report. A CRAC shown in red is above its nominal capacity and needs a closer look.
  4. In the example, supply air is much colder than necessary, so most racks fall below the recommended range. The presenter notes this will not harm equipment but wastes energy.
  5. The 3D viewer: shortcut keys for views, N to turn off perspective, a view manager to hide surfaces, and P to save an image at the window’s size.
  6. The plots: the surface and hybrid body-fitted mesh, ASHRAE recommended, allowable and full-range inlet temperature, temperature and pressure planes, flow rate on tiles, and path lines from CRACs, tiles and racks. In the example, high velocity under a shallow floor near the cooling units lowers the tile flow, with some short circuiting back to the units.
  7. Customizing: turning on modify post in plot setup to add velocity contours, animations, clouds, up to 10 extra planes per group (positioned using the cursor coordinates), and scale limits. Post-only reruns skip the solve.
  8. Sharing: the hyperlink switch emails a URL for each image, which can sit behind a picture in a Word document or PDF to open the view in 3D. Report units can be changed under settings, though images do not change.
