[Users] Output file for one specific grid point

[Severin Frank]

Dear all,

is there a nice way to create an output for 1 specific grid point?

I want to generate a long term time evolution for a specific value 
SWTNS::Xi(,j,k) for only one specific grid point (e.g. 
(i,j,k)=(27,17,27)) without collecting data for an entire line as 
IOASCII::out1D would do.

Does anyone know how this can be achieved?

Thanks a lot and best regards,

Severin Frank
