Please contact with AKL company to purchase a copy of FlowDesigner.

Please check the link of MaeLab, the University of Tokyo for more information.

Please ALWAYS restart FlowDesigner BEFORE Grasshopper!

Please use 32-bit Rhino, 64-bit version is sometimes unstable with FlowDesigner.


As Grasshopper3D is an excellent parametric modeling platform, this tool certainly features its geometry abilities. With this tool, you can convert the geometries (polygon & box) into objects in FlowDesigner (inlet, volume source, etc.) and set the properties. The modification you did in Grasshopper3D can be immediately reflected in FlowDesigner. The efficiency of modeling can be several times higher. (Image.1)


Many configurations of FlowDesigner can be set in Grasshopper3D, including analysis range, external wind and analysis mesh division. (Image.2)

CSV Results

This tool can make use of the CSV output functions in FlowDesigner. The results can be visualized in Rhinoceros. A component was designed to pick up the results in a certain section, just like in FlowDesigner. (Image.3)

Automatic Loop

A counter will be triggered when the calculation finishes, which can be used to change the parameters and trigger the simulation. Automatic looping can be realized. (Image.4)
