MpCCI Mapper

The crash behavior of relevant components does not only depend on design geometry and material properties, but is also influenced by manufacturing history. A failure can be caused by local thickness reduction or residual stress peaks which are a result of the stamping process. This failure can limit the functionality of the entire component. In particular, the local hardening step can induce gradients in the phase proportions or influence residual stresses – and thus influence the dynamic behavior of the crash part.

MpCCI Mapper allows to check the geometric compliance of two models by calculating the local distances between them. The (automatic) mesh alignment helps to adjust the positions of two models if they are not in a non-conformal coordinate system. A robust mapping algorithm enables the transfer of various physical quantities (with nodal-, element- or shell-layer based locations) for all standard shell element and mesh types. The mapping works for different integration types as well as for different number of integration points in thickness direction for source and target model.

By using a so-called »back-mapping validation« the user can check and estimate the influence of locally incompatible mesh discretizations on the mapping quality. In a similar way, the user may compare experimental data (e.g. from forming analysis tools like Atos, Argus, or Autogrid) with simulation results. The MpCCI Mapper can provide local quantity difference images, which then can be used to adjust the parameters of the forming simulation.


The MpCCI Mapper comes with a graphical user interface where all relevant parameters for the mapping can be set. The usage of the tool is quite simple: after selecting the models and parts some choices concerning algorithms and parameters have to be made.  The immediate visualization of the results makes it possible to detect model errors or bad mapping results due to parameter problems. The user can identify the critical areas and start a new mapping process.

The graphical user interface of the MpCCI Mapper is split up in four major regions. The main viewport where loaded models and quantities can be interactively displayed is located on left of the window. A list of buttons above the viewport form the so called 'toolbar‘ where basic operations of the MpCCI Mapper are linked. A panel region is displayed nearby the viewport, where the mapping, the list of meshes and parts, the validation of mapping and also certain quantities can be analyzed. At the bottom of the window, a single button is present which is responsible for starting mapping, validation, or analysis processes.

MpCCI Mapper uses a k-nearest-node mapping algorithm (default k = 4) that combines robustness with data smooting. At times where averaging of certain entities is not wanted or when data smoothing shall be increased, MpCCI Mapper allows to adjust the number of data points used for interpolation.
