It all Starts with Flow Analysis

Guill performs this on all tooling as a first step
Guill utilizes Fluid Dynamics software from COSMOSFloWorks in order to analyze the flow characteristics of all of our designs.
COSMOSFloWorks functions directly inside of SolidWorks. This enables geometry changes to be calculated immediately. Exporting the CAD models to an external program is not necessary.
