VOF fraction field

scalar f[];

Input filename buffer

char filename[80];

Main Function

Extract facets from a saved simulation state.

Parameters

• a: Argument count
• arguments: Command-line arguments
  • arguments[1]: Simulation file path

Process

1. Load simulation file
2. Extract facets from VOF field
3. Output to stderr

int main(int a, char const *arguments[]) {
  sprintf(filename, "%s", arguments[1]);
  restore(file = filename);

  FILE * fp = ferr;
  output_facets(f, fp);

  fflush(fp);
  fclose(fp);
}
