Non-associative workflow

The following steps define the general workflow for creating an assembly FEM that is not associated with any existing CAD assembly.

Step	Summary	Detailed help topic
1. Create or obtain component FEMs.	Component FEMs may be geometry-based FEMs, non-geometry-based FEMs, imported meshes, or manual meshes. These comprise the assembly you want to model.
2. In Pre/Post, create an assembly FEM.	In the New Assembly FEM dialog box, clear the Map to part check box to create a non-associative assembly FEM.	Create an assembly FEM file
3. Build your assembly FEM structure.	Add existing component FEMs to the assembly FEM to define its structure. You can also add a new, empty FEM to the assembly FEM.As needed, reposition the component FEMs.	Add an existing FEM to an assembly FEMAdd a new FEM to an assembly FEMPositioning component and subassembly FEMs within an assembly FEMPosition a component or subassembly FEM using coordinate systems within an assembly FEM
4. Connect component FEMs.	Using 1D Connections or the available manual meshing tools, connect the component FEMs to define the system model.	Connecting component FEMs
5. Refine the assembly FEM.	You can continue to refine your assembly FEM as needed. For example, you can:Replace component FEMs with alternative geometry or mesh representations.Override component FEM properties to define unique physical and material properties for the system analysis.Control component FEM loading to manage system resources.	Replace component FEMsOverride component FEM propertiesReplace component FEMsManage component FEM loading
6. Resolve label conflicts.	Following any change to the assembly FEM structure or its component FEMs, check for conflicting node, element, or coordinate system labels. Apply offsets to resolve any conflicts.	Resolve label conflicts in your assembly FEM files
7. Create a Simulation file based on your assembly FEM.	In the Simulation Navigator, right-click the assembly FEM node and choose New Simulation. You apply loads and boundary conditions, define your solution, and solve the model as in any other Simulation file.
(Optional) Import simulation entities from component FEM simulations.	If there are simulations defined for component FEMs or subassembly FEMs, you can import selected loads, constraints, and so on from the component's simulation into the assembly FEMs simulation.For more information, see Importing simulation entities.
