Boundary conditions > Using fields and expressions to define boundary conditions
Breakout modeling workflow
The typical workflow for breakout modeling is:
Build a model of a structure, using a coarse mesh.
Solve the model for displacements.
Identify the portion of the model that you want to study further. Make a group of the nodes and elements to study.
In Post processing, save results (for example, displacements) for the group to a .csv file. For more information, see Write identified data to a spreadsheet or CSV file.
Create a new FEM that includes geometry that defines the nodes and elements in the group.
Mesh the new model with a finer mesh.
Create boundary conditions on the borders of the breakout model. For example, to define an enforced displacement, create a field that uses the displacement results from the original analysis.
Solve the new model, and review the results.
