If you have the time to help me, I'll be greatful...

Macros record your moviments in GUI pannel so, after starting to record them (/execute command/macro/start) make as u're appling the condition for the first time(i.e.: click on define/udf/execute on demand --->hook your udf --->execute it). After stop your macro. and set it as a running command on execute window (each time step for example). run your simulation.

It may run.I hope. Regards A
