Hi,

Automatic export is only available for transient calculations. If you want to export data in file format other than .dat every X iterations, I guess you have to write a DEFINE_EXECUTE_AT_END udf.

Ok now I don't understand, your 1st post implied that your model is steady-state, and now you want to export time-dependent results...

For time-dependent exports you got everything your looking for in the GUI.

ya ya i think i was wrong. this should be transient problem not steady state.
but the question remains, how to give an oscillatory boundary conditions.

The question doesn't remain, in each post you're asking a new question!

Clarify what your looking for, search the forum thoroughly for 'oscillatory' etc., tell us what you've tried so far, and then ask a precise question please.
