| Type | Intent | Optional | Attributes | Name | ||
|---|---|---|---|---|---|---|
| class(glacier), | intent(in) | :: | this | |||
| class(glacier), | intent(in), | dimension(:) | :: | previous_states | The states of the glacier in the previous time steps. The first element of the array should be the most recent. The default implementation will only make use of the most recent state, but the fact that this is an array allows overriding methods to use older states for higher-order integration methods. |
|
| class(scalar_field), | intent(in) | :: | melt_rate | Thickness of the ice above the glacier |
||
| class(scalar_field), | intent(in) | :: | basal_drag_parameter | A paramter, e.g. coefficient of friction, needed to calculate the drag on basal surface of the glacier. |
||
| real(kind=r8), | intent(in) | :: | water_density | The density of the water below the glacier |
The residual of the system of equations describing the glacier
