A SIMULIA e-Learning Resource
Created using Abaqus 6.5 and 6.12
Abaqus provides the capability to import a deformed mesh and its associated material state from Abaqus/Standard into Abaqus/Explicit and vice versa.
This capability can significantly reduce the analysis time required when a portion of your analysis history is best suited for the Abaqus/Standard solver (e.g. the inflation and steady state rolling of a tire) and another portion of your analysis history is best suited for the Abaqus/Explicit solver (e.g., the rolling tire hits a bump).
This capability is particularly useful in manufacturing problems; for example, the entire sheet metal forming process (which requires an initial preloading, forming, and subsequent springback) can be analyzed. In this case the initial preloading can be simulated with Abaqus/Standard using a static procedure and the subsequent forming process can be simulated with Abaqus/Explicit. Finally, the springback analysis can be performed with Abaqus/Standard.
Abaqus also provides the capability to transfer desired results and model information from an Abaqus/Standard analysis to a new Abaqus/Standard analysis or from an Abaqus/Explicit analysis to a new Abaqus/Explicit analysis, where additional model definitions may be specified before the analysis is continued. For example, during an assembly process an analyst may first be interested in the local behavior of a particular component but later is concerned with the behavior of the assembled product. In this case the local behavior can first be analyzed in an Abaqus/Standard or Abaqus/Explicit analysis. Subsequently, the model information and results from this analysis can be transferred to a second Abaqus/Standard or Abaqus/Explicit analysis, where additional model definitions for the other components can be specified, and the behavior of the entire product can then be analyzed.
Narrated Video
This demonstration was created using Abaqus 6.5, however the modeling concepts demonstrated still apply in Abaqus/CAE today.
The following video contains:
- Introduction (0-0:16)
- A demonstration of importing analysis results from a previous Abaqus analysis
--- Visualize the results of the Abaqus/Explicit bracket forming analysis (0:16-0:44)
--- Copy the forming model to a new model for the springback analysis (Abaqus/Standard) (0:44-0:50)
--- Modify the springback model:
----- Change the analysis type to static (0:50-1:00)
----- Delete the rigid dies and the associated sets, surfaces, contact, and boundary conditions (1:00-1:23)
----- Fix a corner of the blank in the 2-direction to prevent rigid body motion (1:23-1:53)
----- Create an initial state field to import the final state of the forming analysis (1:53-2:23)
--- Create and submit a job for the springback analysis (2:23-3:00)
--- Visualize the results of the springback analysis (3:00-3:40)
This demonstration was created using Abaqus 6.5 and can also be found in the Introduction to Abaqus 6.5 web-based training site.

This file includes the example model shown in the demonstration. It also includes the step-by-step instructions (ResultsTransfer-BracketDemo-StepByStep-Abaqus612.pdf) to help you create an Abaqus/Standard spiringback simulation based on the imported final state of an Abaqus/Explicit bracket forming analysis.
This exercise was produced using Abaqus 6.12.
