Mapping Data from a Simulation History onto an Imported CAE Model

You can map data from a solution history (.simh) file onto an imported CAE model, and then automatically export the data via .mat format. The following steps illustrate this technique with a specific case.

  1. Import a CAE model from an external transient post-processing file (often from NASTRAN). This comes in as a standard imported model. This imported model has on it the following fields:
    • ImportedCellIDList
    • ImportedFaceNumList
  2. Create a derived data set with geometry cloned from this CAE model, and with fields mapped from the solution history representation:
    1. Right-click the Tools > Data Set Functions node and create a surface time history.
    2. In the properties of the surface time history node, specify the Start Signal and End Signal times to be the ones from the CAE model. Set Interpolation Method to Nearest Neighbor.
    3. Right-click the Imported sub-node of the surface time history node, and select New derived data from surface to create a Multi-Point Time History node.
    4. Set the properties of the Multi-Point Time History node as follows:
      Property Setting
      Representation The solution history representation
      Data Surfaces 1 The surface that is exported to the .simh file
      Target Surfaces The surface from the CAE model
      Field Function Pressure or Temperature
    5. Right-click the Multi-Point Time History node and select Update Output.
  3. Export the .mat file containing the cloned geometry and the mapped fields, ImportedCellIDList and/or ImportedFaceNumList:
    1. Right-click the Multi-Point Time History node and select Export Field.
    2. In the Save dialog, export the data as a .mat file.
