I have created a climate file using 3 years of data in the CreateClimate.xls spreadsheet. It exports to .WAC fine and loads into WUFI.
When I review the data in WUFI all but the RH is incorrect. In the Temperature/Relative Humidity dialog the temperature graph is incorrect, it is too flat with no low temperatures. In climate analysis it gives me uniform solar radiation and diving rain in all parts of the circle.
.WAC file imports incorrectly
Re: .WAC file imports incorrectly
It seems there's something in the file which WUFI does not understand correctly. Could you post the beginning of the WAC file (i.e. the header lines and the first few data lines)?robbin wrote:When I review the data in WUFI all but the RH is incorrect.

You are using 'measured' values for the solar radiation (ISM) and for the rain (RM).
That is, they are supposed to have been measured as incident on a given surface with a certain inclination and orientation, and it tells WUFI that no directional conversion to a different orientation shall be attempted. In fact, WUFI cannot use them to compute what would be incident on a differently oriented surface. For example, if your ISM has been measured on a vertical west-facing wall, it is only valid for such a wall and WUFI cannot know what would have been incident on, say, a south-facing wall, because for such a directional conversion the diffuse and the direct radiation components would have to be known separately.
Since no directional conversions are possible with the radiation and rain data measured on a particular surface, the radiation and rain roses cannot be filled with any meaningful data.
And you can only do a simulation for a surface with the same orientation and inclination as that on which the radiation and rain data have been measured.
I cannot tell from the four data lines what your temperature plot looks like. But I guess that if it looks strange it's probably just a quirk in the display of the graph. By looking at the exterior air temperature curve in the result graphs (or by exporting it to an ASCII file via the ASCII export) you can test whether WUFI read your data correctly.
