Once installed, BLASTER is initialized using the following lines:
|
|
|
|
```python
|
|
|
|
from blaster.blast.api.blaster_api import init_blaster
|
|
|
|
_blast = init_blaster(cfg, icfg, iSolverName, task)
|
|
|
|
```
|
|
|
|
where the parameters are...
|
|
|
|
where:
|
|
|
|
- `_blast` is a Python dictionary containing the objects required to run BLASTER
|
|
|
|
- `cfg` is a Python dictionary that configures the viscous solver
|
|
|
|
- `icfg` is a Python dictionary that configures the inviscid solver (e.g. see [DART](https://gitlab.uliege.be/am-dept/dartflo/-/wikis/use_api_core))
|
|
|
|
- `iSolverName` is the name of the inviscid solver (available options: `'DART'`)
|
|
|
|
- `task` is the type of calculation to be made (available options: `'analysis'`, `'optimization'`)
|
|
|
|
|
|
|
|
This will return... |

The configuration dictionary `cfg`consists of the parameters defined here under:
|
|
|
|
```python
|
|
|
|
cfg = {
|
|
|
|
'Re': float # Flow Reynolds number.
|
|
|
|
'Minf': float # Freestream Mach number (only used for time step computation).
|
|
|
|
'CFL0': float # Initial CFL number.
|
|
|
|
'Verb': int # Verbosity level of the viscous solver.
|
|
|
|
'xtrF': [float, float] # Forced transition location [upper, lower].
|
|
|
|
'couplIter': int # Maximum number of coupling iterations.
|
|
|
|
'couplTol': float # Tolerance to end computation (drag count between 2 iterations).
|
|
|
|
'iterPrint': int # Number of iterations between which the coupler outputs its state.
|
|
|
|
'resetInv': bool # Resets the inviscid solver at each iteration (True), reuses previous state as initial condition (False).
|
|
|
|
}
|
|
|
|
```
|
|
|
|
|
|
|
|
The return dictionary `_blast` contains:
|
|
|
|
- `coupler`: the coupler driving the viscous inviscid process
|
|
|
|
- `isol`: the interface of the inviscid solver (see `blast/interfaces/DSolversInterface.py`)
|
|
|
|
- `vsol`: the viscous solver
|
|
|
|
- `adj`: the coupled viscous inviscid adjoint solver
|
|
|
|
|
|
|
|
|
|
|
|
A viscous inviscid solution is then obtained by:
|
|
|
|
```python
|
|
|
|
coupler.run()
|
|
|
|
``` |
