External CFD Wind Pressure Error

[richardd]

I am looking at wind pressures on the exterior facade of a building. I ran an external CFD simulation with 150 ft/s velocity. The default pressure key ranges from -81.177 to 32.118 (pressure in in. water) in the MicroFlo viewer. Two questions:

1. Are the pressure units referring to Class/Design Pressure or some other standard?
2. When I try to set a custom range (in slice display settings) I get an error:

"Invalid entry: Please enter a value in the range -4.01 to 4.01"

Why do I get this message when the default range is already well beyond these limits?
If the units are, indeed, in terms of Class/Design pressure then I would want to look at pressures beyond 5.00 (at minimum). Is there a way for me to achieve this?

Thank you in advance for your help.

I have looked in to a similar problem and had no problems setting the limits. The limits are set by the recorded values in the field.

Thank you for your reply. However, I don't think that is the problem. I understand that the range in pressure values that the software generates by itself will vary from project to project and that this inherently gives a different default range scale, but when I try to set the range to custom settings I am limited to using values between -4.01 and 4.01. This is true no matter the project. It seems like this is an error in the software that needs to be repaired, since the default pressure values on some projects (as I described previously) are well outside these bounds.
