This is an example UDF for a mask, where you would gradually set the value from 0 near the source to 1 away from the source.

DEFINE_SOURCE_MASK(src_mask_define, c, t)
{
  real xc[3];

  real arg, fun;

  C_CENTROID(xc,c,t);
 
arg = [expression that varies your source from 0 to 1 depending on the location relative to your source]

  fun = arg;

  return(fun);
}
