Studies

A VacTran study is an interactive dialog that enables rapid parametric modeling.

Simple System Study

This is a very simple representation of a vacuum system that enables rough order of magnitude calculations.  Use a System Model to use multiple pipes, pumping stages, or gas loads.

---

Change any variable in the dialog, then click on Solve calculated value to create a pump down curve.  The curve will be shown in the Main Graph Window.

The five tabs at the bottom of the window let you select the variable to solve.  For example, click on the volume tab, then click on Solve calculated value to solve for the vessel volume that meets all other criteria.

Series and parallel conductance studies

Models a group of conductances while varying the diameter, generates a conductance graph
