MpCCI FSIMapper

The MpCCI FSIMapper is able to read various CFD export formats as well as input decks for Abaqus, Ansys, and Nastran. The two meshes between which the interpolation shall take place have to be 2-dimensional surface meshes in a 3-dimensional space. The quantities that can be read and mapped are film temperature, wall heat transfer coefficient, the wall heat flux, standard and complex pressure, and force densities.

A specific feature is the possibility to compute »Average over Rotation Axis«: if the CFD model uses the frozen-rotor option, the quantity values from the frozen-rotor computations will be averaged and these quantity values will be mapped to the CSM model. The mapped quantity values can be imported into Abaqus or Nastran models.

Furthermore, it is possible to compare two geometries with the MpCCI FSIMapper.

Concept

The MpCCI FSIMapper 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. After the mapping, the results and the original values are loaded into the MpCCI Visualizer.

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.

Additionally, the MpCCI FSIMapper can be used as a batch tool. The parameters and settings that are normally made in the GUI can be defined in a simple ASCII configuration file.

The tool is available for Windows and Linux 64–bit machines (Windows 32-bit until FSIMapper 4.4.2) in graphical and batch mode.
