◆ processsolution()

subroutine connectionbuildermodule::processsolution ( class(connectionbuildertype this,
class(basesolutiontype), pointer  solution

This routine processes all exchanges in a solution and, when required, creates model connections of the proper type (GWF-GWF, GWT-GWT, ...) for a subset. It removes this subset of exchanges from the solution and replaces them with the created connections.

Parameters
thisthe connection builder object
solutionthe solution for which the exchanges are processed
