# TSBasicSymplecticSetType
Set the type of the basic symplectic method 
## Synopsis
```
#include "petscts.h"   
PetscErrorCode TSBasicSymplecticSetType(TS ts, TSBasicSymplecticType bsymptype)
```
Logically Collective on TS


## Input Parameters

- ***ts -*** timestepping context
- ***bsymptype -*** type of the symplectic scheme



## Options Database

- ***-ts_basicsymplectic_type <scheme> -*** select the scheme



## Notes
The symplectic solver always expects a two-way splitting with the split names being "position" and "momentum". Each split is associated with an IS object and a sub-TS
that is intended to store the user-provided RHS function.
