# TSDMSwarmMonitorMoments
Monitors the first three moments of a `DMSWARM` being evolved by the `TS` 
## Synopsis
```
#include "petscts.h"  
PetscErrorCode TSDMSwarmMonitorMoments(TS ts, PetscInt step, PetscReal t, Vec U, PetscViewerAndFormat *vf)
```
Not collective


## Input Parameters

- ***ts   -*** the `TS` context
- ***step -*** current timestep
- ***t    -*** current time
- ***u    -*** current solution
- ***ctx  -*** not used



## Options Database Key

- ***-ts_dmswarm_monitor_moments -*** Monitor moments of particle distribution





## Notes
This requires a `DMSWARM` be attached to the `TS`.

This is not called directly by users, rather one calls `TSMonitorSet()`, with this function as an argument, to cause the monitor
to be used during the TS integration.
