Hi
I'm trying to study the flare flame-out dispersion pattern and concentration of a hydrocarbon gas incorporating the model on a map using PHAST v6.51.
I've set up my model using 'User Defined Source', input the mixture of my hydrocarbon gas, defined the release scenario as a leak, setting a concentration of interest as 3000ppm, time 3600s, a vertical outdoor release direction. I'm just using the global weather wind speeds at the moment.
After running the model, I'm able to view the graphs such as the side view, cross section, jet fire, explosions and flash fire. I'm interested to see the plan view concentration transposed on a map which I've inserted using the raster image set. However I'm not seeing the concentration plotted on the map after I run the model, even after I've played the dynamic cloud control button. The map is just showing a model dot which the legend defines as my model but there is no concentration of interest (3000ppm) at time of 3600s.
By the way, here's how I inserted my raster image: Under the Map tab, insert raster image, placement mode - interactive. I didn't check anything on the handling a co-ordinate system offset. Under base storage type - i selected projection; projection space as rectangular grid. Then with a click and drag of the mouse, I selected the area which I had wanted the map to be on the Map. The map appears on the screen.
If you look into the PHAST example studies, e.g. when you run the Chlorine Vapor Leak model; click on view graph; then select F 1.5m/s and go to the Map tab, you can see the concentration at time: 964.1s of 30, 60, 150, 300 ppm being plotted respectively on the map as well as the model dot.
My question is, how can I plot my concentration of interest on the map? It doesn't seem to appear. Hope I've given enough info. Appreciate if any experts can help me out. Thanks.
Cheers!
