+# AIAA Applied Aerodynamics Surrogate Modeling - Case 4
+
+This folder contains the data available for the AIAA Applied Surrogate Modeling
+benchmark case 4 which consists out of in total 149 surface solutions solving
+the RANS equations. The corresponding AIAA SciTech2025 Paper provides more
+information about the dataset.
+
+The data is split in training and test samples in separat folders. All are
+available in two hdf5 files, one for training samples and one for test samples.
+These files provide parameter information (Mach, AoA, innerAileron,
+outerAileron, htp angle and elevator) and surface values (cp, cf, coords,
+normals, surface areas). An additional file is available providing connectivity
+information.
+
+Note that, if validation data is needed for your surrogate modeling technique
+these should be taken from the training samples.
+
+In addition to the data a simple python script *h5Import_NASA-CRM.py* is
+available. This file provides a function which reads the data from h5 file. It
+returns a dictionary with the sample numbers as keys. Under each key another 
+dictionary is available with global informations such as parameters values and
+global coefficients and surface solutions as numpy arrays.
