In dKvale/bpip: Interface to EPA's downwash model BPIP

Running BPIP for a rotated building

This example creates downwash inputs for a 10x10x10 building that is rotated 45 degrees and located 20 meters West of the air emissions source.

Install BPIP to a new EPA folder in working directory

library(installEPA)

install_epa("bpip", dir = "EPA")

Create new bpip table

library(bpip)
builds <- new_bpip()

library(knitr)
kable(builds)

Adjust building parameters

builds$bld_rotation      <- 45

builds$length_x          <- 10

builds$angle_from_source <- 270 

kable(builds)

Plot building

plot_bpip(builds)

Add a building

builds <- rbind(builds, builds)

builds$building[2]          <- "Bld_2"

builds$angle_from_source[2] <- 90

builds$bld_rotation[2]      <- 60

builds$bld_height[2]        <- 15

kable(builds)

Plot buildings

plot_bpip(builds)

Create bpip input file

write_bpip(builds, "rotated_building.bpi")

Run bpip

run_bpip("rotated_building.bpi", "rotated_results", exe_folder = "EPA/")

Read results

results <- read_bpip_out(file = "rotated_results.out", as_text = FALSE)

kable(results)
