Transformer inductance value

Hi,
I had used your PIXI Designer tool and i am able to get that Nominal Primary Inductance, µH but not secondary inductance coil value please suggest how can i calculate?
Also i wanted to know the coupling coefficient value of the transfomer which is not mention in your design tool please suggest me or how can i calculate?
I need to follow some safety UL508C standards,should i need take care something while designing the transfomer?
Thanks.

The secondary inductance should be equal to primary inductance times square of the turns ratio (NS/NP)^2
The coupling co-efficient is related to leakage inductance which should be measured on your transformer
About safety standards, PI Expert tries to follow guidelines from UL1950
