The Import calculation file function allows you to import a calculation file (see section Calculation module's input data file). The file can be a “complete” calculatable calculation file or a file just containing definitions of the geometry for the model, e.g. manufactured from a CAD file or exported from a network information system. The import adds information to the model and does not need to be a complete model. You must observe what names pipes and nodes have in the import file in relation to which names you use for pipes and nodes in the model database to which you are importing. If nodes/pipes exist with the same names in the import file and the database, the node in the database receives the coordinates which it has in the import file. Likewise, the pipe in the database is given the geometry which it has in the import file.
An import file cannot fully build up all boundary conditions in the model database. For e.g. pumps, any reference value to which the pump is regulated cannot be set up by the import function. This has to be added manually to the model after importing.
