[tag] prefix

Template for the prefix which will be prepended to the output files. Allowed template expressions are:

• {:meshname}
• {:timestep}
• {:time}
• {:iteration}.

Default value: {:meshname}

Remark: The name of the pvd-file will be constructed out of the prefix.

Furthermore, it is possible to specify the format of the expressions above. For instance {:0>3timestep} results in a 3-digit output, if necessary with preceding zeros. Also the time output can be formatted using the typical floating point precision (for instance 0.4) and type (e, E, f, F, g, G) modifiers.
