### 1.1.2. Principle

ANSYS Composite PrepPost (ACP) is an add-in to ANSYS Workbench and is integrated with the standard analysis features. The entire workflow for composite structure can be completed from design to final information production as a result.

The geometry of the tooling surfaces of a composite structure is the basis for analysis and production. Based on this geometry and a FE mesh, the boundary conditions and composite definitions are applied to the structure in the pre-processing stage. After a completed solution, the post-processing is used to evaluate the performance of the design and laminate. In the case of an insufficient design or material failure, the geometry or laminate has to be modified and the evaluation is repeated.

ACP has a pre- and post-processing mode. In the pre-processing mode, all composite definitions can be created and are mapped to the geometry (FE mesh). These composite definitions are transferred to the FE model and the solver input file. In the post-processing mode, after a completed solution and the import of the result file(s), post-processing results (failure, safety, strains and stresses) can be evaluated and visualized.
