Can I stamp calculations using this model? I have no clue what is going on in this black box model, and therefore am refusing to put my seal to the output of them.
In fact, I would contend that any registered engineer who does not know what is going on in the black box is putting his license on the line by sealing the output.
I am wondering if anybody else feels the same.

As for stamping its output, I would, but as a report on the output, not a calculation.

I work in Oregon and have never used WWHM. What little I've seen of it seems pretty obscure, however. If I were "required" to use it I would, as Civilperson suggests,check the results by some other method to be certain they are reasonable. If they seem to be, then I'd have no problem stamping the design. Remember, you are certifying the design, you are not, and as far as I know,not required to certify that every calculation done to arrive at the final design is correct in every detail.
If you were required to certify every detail you would have to do all calculations by "hand" since you don't even know exactly what goes in inside your electronic calculator,or a spreadsheet,or any other computer program you didn't personally write.
good luck

At times the program can be buggy, but overall it isn't a bad program. I wouldn't hesitate to stamp a report with the output, but I would definitely make sure my input was correct.
I have used this program for 6+ years so if you have any additional questions please don't hesitate to ask.
