Reduced C code is:

typedef struct {
  double masses[0];
  int species_offset[];
} LandauCtx;
LandauCtx ProcessOptions_ctx;
ProcessOptions_ctx_2;
LandauCreateVelocitySpace_v0_grid[];
LandauCreateVelocitySpace() {
  int PetscOptionsObject_0 = 0;
  for (;;)
    for (int grid; ProcessOptions_ctx_2; grid++)
      LandauCreateVelocitySpace_v0_grid[grid] *= sqrt(
          ProcessOptions_ctx.masses[ProcessOptions_ctx.species_offset[grid]]);
}
