Any interest in Vehicle Drag Calculator? (Android App)

Project: Van+Large Trailer cd 0.36 to 0.23, CFD test
Asias explains: "We are trying to substitute large 7 meter van (with 1200 kg payload) by a medium van + aerodynamic trailer. Before we were getting aprox 22 mpg at 65 mph, but we want go somewhere near 33 mpg." Using a CFD model (computational fluid dynamics), he documents a test beginning at 0.36 cd (only the van) resulting in a 0.233 cd with the trailer attached and gap filled.
