Re: Repeating Captex #2

Please use "Save as" for both Control and Setup files and then you can "Retrieve" those.
Please change the file names as you may want to have the original files intact.

Re: Differences in graphs

Such differences are possible because random numbers are used.
The random numbers are likely to be different due to different Fortran compilers, different versions of them, and even different computer configurations.

Re: Dilution Factors

Unit release RATE is used to calculate the dilution factors. The released mass does not have to be unit mass. So a 2-hour release can be run with the unit rate for the two hours. If the release rates for the two hours are different, two different runs with unit release rate for each hour should be r...

Re: Calculating air volume over small sampler

It seems that your air sampler is a passive one which does not have intake control at the inlet. In this case, you will only need to know the wind speed (the component perpendicular to the sampler surface) at the sampler location to calculate the air flux (F=Vp x Area). Then integrating the flux ove...
