How to simulate a resistor in Microstripes?

Hello

I am designing a Wilkinson power divider these days. I will have to simulate it in Microstripes 7.5. Anyone can tell me how to simulate the resistors?

I have read many times about the chapter 'wire and circuits' in the reference manual but still cannot understand.

Best Regards.
