m3dc1_meshgen deprecated

  • m3dc1_meshgen has been deprecated and is no longer supported by the RPI SCOREC group

​

  • This capability has been replaced by m3dc1_mfmgen, which is more general and flexible

​

  • m3dc1_mfmgen is not backwards compatible with m3dc1_meshgen input files. Input format is described in the M3D-C1 documentation.
    • Andreas has written a script convert_meshgen_input to translate m3dc1_meshgen input files into m3dc1_mfmgen input files.
