You can download and install Zorba from this Link Once installed it will run in demo mode which allows you to see how it works. However in demo mode you can not change the inputs such as thickness or flow resistivity of materials, Zorba uses the initial default values. You also can not print or save or open files.
If you are interested in testing Zorba more closely you can email us for a temporary licence. This allows you to input your own values for thickness, flow resistivity, hole diameters and spacings, and satisfy yourself that Zorba will be useful to you. You can not print or save files in trial mode.
