  9. What is GOURMET?
    GOURMET is a common platform of for individual simulators. GOURMET provides a common graphical user interface for all simulation programs. GOURMET is an editor of the input data, a viewer of the output data, a tool to make graphs and animations, and most importantly a place for various simulation programs to meet and exchange the information they have. These services can be customized and enhanced by users. New simulation programs can be easily connected to GOURMET by writing the input and output files in a certain text file format called UDF (User Definable Format).
  10. What is UDF?
    UDF is a general file format used by simulation engines in OCTA. You can view, edit and analyze UDF file by using GOURMET, the user interface software included in OCTA. UDF is a plain text file, and consists of definition part and data part. In the definition part, you can define the data structure of your engine in a simple and natural way. The data in UDF can be easily accessed and modified by using UDF interface libraries for C/C++, Fortran and Python. KAPSEL uses UDF, and the detailed information on UDF for KAPSEL is explained in detail in “Data File“.
  11. How can I read and write UDF files?
    The UDF file is a text file, but can be treated as a random access storage without paying attention to its file structure. This means that any data in UDF can be read and written in any order from user programs (C/C++, Fortran, Python). To facilitate I/O from/to the UDF file, two service libraries are provided.
    • libplatform: This is the library needed to read and write UDF files from C/C++ and Fortran programs. One can find such an example in KAPSEL source code, which is written in C++.
    • Python UDF Manager: This is the library needed to read and write UDF files from Python scripts.
