 bool overwrite\_existing

If true, then existing data objects will be replaced.

This option is used by transferData





<a id="ae79cc32e0a89d7a67bb2cfc469d95e6a"></a>## [◆ ](#ae79cc32e0a89d7a67bb2cfc469d95e6a)transferred\_data\_ident\_prefix

 string transferred\_data\_ident\_prefix

The prefix for re-transferred data.

transferData is able to transfer the data to the new database, and to transfer the same data back This strategy allows to check the error that is obtained when transferring data between two meshes, since one can compare it with the original data on the same mesh. If the prefix is an empty string, then no data will be created. Else one choses the new quantity ident as "prefix\[original\_quantity\_ident\]"
