Описание

The FEM Analysis could be seen as a container that holds all objects of a Finite Element Analysis. It is mandatory to have an Analysis container that holds all the needed objects. At least one of the following objects (apart from the mesh) is necessary for a mechanical analysis:

• solid material,
• fixed boundary condition or displacement boundary condition or rigid body constraint.

Применение

1. There are several ways to invoke the command:
   • Press the Analysis container button.
   • Select the Model → Analysis container‏‎ option from the menu.
   • Use the keyboard shortcut: S then A.
2. A new Analysis container is created and set to active.
3. Other objects can be added or removed from the Analysis container by drag and drop.
4. To add new FEM objects to the document the Analysis has to be active. Double-clicking on the Analysis container activates the analysis.

Опции

• Up to date there is no option to choose.

Свойства

• ДанныеOutpuDir: Specifies the working directory of the analysis

Программирование

most code here is deprecated in 0.17.

• new analysis

MechanicalAnalysis.makeMechanicalAnalysis( name )

• add object to the analysis

App.ActiveDocument.MechanicalAnalysis.Member = App.ActiveDocument.MechanicalAnalysis.Member + [ (object) ]

• remove object from the analysis

member = App.ActiveDocument.MechanicalAnalysis.Member
member.remove( documentobject )
 App.ActiveDocument.MechanicalAnalysis.Member = member

Примеры:

import MechanicalAnalysis
analysis = MechanicalAnalysis.makeMechanicalAnalysis("MechanicalAnalysis")
FemGui.setActiveAnalysis(analysis)

addobj = App.ActiveDocument.getObject("MechanicalMaterial")
App.ActiveDocument.MechanicalAnalysis.Member = App.ActiveDocument.MechanicalAnalysis.Member + [addobj]

removeobj = App.ActiveDocument.getObject("MechanicalMaterial")
member = App.ActiveDocument.MechanicalAnalysis.Member
member.remove(removeobj)
App.ActiveDocument.MechanicalAnalysis.Member = member
