Hi everyone,
We've just released a feature that we've had in development for awhile now, support for angled walls. This allows you to model most any data center shape. In addition to the rectangle cutouts that are already present, there are now triangle cutouts you can use to model your data center room. In IT Advisor CFD, you can check out the built in Reference Project -> Complex Room Shape to see what is possible.

Hi everyone,
We are holding a training next week for the new airflow metrics in IT Advisor CFD. This will be a comprehensive overview of the IT airflow effectiveness metrics and the cooler airflow efficiency metrics, both at the equipment and the room level.
Please register with the link below. You'll then receive an email with a calendar entry/ Outlook meeting invitation for the training.

We'll also have time for Q&A.
Thanks!

We just a released a new feature to assist with laying out your data center in IT Advisor CFD. You can now use an image as a template to guide the placement of equipment and defining the room shape.
After you add a template, you can precisely scale it using the 'Set Reference Dimension' tool. Position the template where you want it in relation to the IT Advisor CFD room using the mouse, and then begin laying out your data center. Once the template is scaled and positioned, lock it in place to keep it where you want it as you finish your layout.
We've added a few other touches such as template opacity and floor grid color to help view the template in relation to the IT Advisor CFD room.
Please check it out and we hope you find this useful!
Note that the Template feature will be available to paying customers but not partners with the limited, free version. Paying customers continue to get the unlimited version with all new features.

The Room menu now shows airflow leakage details for the raised floor and dropped ceiling.
We havenβt changed any calculations, but here is some additional background information. The airflow leakage velocity π at any location is related to the pressure drop Ξπ across the raised floor or dropped ceiling by:
Ξπ=π(1/2)ππ 2
where π is the density of air (we assume 1.2 kg/m3 at seal level) and π is the dimensionless loss coefficient. We compute π as a function of open area π½ for all resistances in EcoStruxure IT Advisor CFD from [1]:
π=(1/π½ 2.3 )(1βπ½)
Note that π½ in the above equation is a decimal value, not a percentage. For example, 0.01 instead of 1%. Finally, % open area values selected for the various raised floor and dropped ceiling leakage options are based on [2] and [3].
