Delete geometry using QGIS graphical modeler

There is no algorithm to remove a geometry on the QGIS graphical modeler filtering by a parameter. To delete a geometry from QGIS graphical modeler, apply 2 algorithms:

1. Select by Expression
2. Save Selected Features

For example, let's assume that you want to delete a geometry with "City" = 'Barcelona' on the attribute table. As you can't delete the element directly, you'll need to use the opposite expression.

In this example, you'll need to select the elements where "City" != 'Barcelona'.

Save the selected features.

After executing the algorithm, the city of Barcelona won't be in the output layer.
