Freeze Drying Software: "PASSAGE�Freeze Drying SoftwarePassage/FreezeDrying is a computer program designed for the simulation of freeze drying processes in vials and pans.
Passage/FreezeDrying provides modeling of containers with axisymmetric boundary conditions with both primary and secondary drying simulation capabilities. The software also handles containers with asymmetric boundary conditions, as in the case of vials placed in corners or near the walls of freeze-drying ovens. It is currently limited to primary drying simulations.
The user-friendly, interactive preprocessor accepts externally generated meshes and support automatic entry of material properties, process conditions, and display of geometry.
Passage/FreezeDrying also has user-friendly, interactive post-processing modules which display the computed temperature, vapor concentration, water pressure, and glass transition distributions in the form of contour plots and x-y graphs. Animation of sublimation front movements can also be obtained easily.
