- User inputs values based on real or experimental process information. Values for Machine Mode
are typically derived from a process sheet or molding machine screenshots.
- In Machine Mode, the user selects a machine from the Moldex3D Machine database and inputs
the values for simulation based on that machine
- The molding of the part is very process specific in this mode, so therefore the processing should
reflect the real molding process directly.
- When running a simple flow analysis, it is NOT recommended to use this mode as process
information is typically not known at this stage.

Machine Mode will be discussed later for a more comprehensive analysis, but for a simple Flow analysis,
CAE Mode should be used.
2.4.4.2 CAE mode – Simple Flow Analysis
It is recommended to use CAE Mode when only running a flow analysis as the settings are simple and the
user does not need to worry about the preciseness of the process settings.
2.4.4.2.1 Maximum Pressure Limits
In CAE Mode, the user may define a maximum pressure with respect to a real-life machine limitation.
Maximum Injection Pressure and Maximum Packing Pressure represent the pressure ceiling in simulation.
If the filling pressure increases to this maximum value, the filling of the part becomes pressure limited and
the packing stage is started. This scenario typically ends up in a short shot.
