Collective on DM
Input Parameters
|  | dm | - The DM | 
|  | time | - The time | 
|  | funcs | - The coordinate functions to evaluate, one per field | 
|  | ctxs | - Optional array of contexts to pass to each coordinate function.  ctxs itself may be null. | 
|  | mode | - The insertion mode for values | 
Output Parameter
