I finished the schematic for my 2.4GHz microstrip Wilkinson power divider. I am moving to the layout and trying to do the EM simulation, but I cannot figure out how to put a lumped element in the layout design. This is the error I am getting:

If anyone could help me put lumped elements into the EM simulation that would be greatly appreciated!! Thanks in advance!

Unless you have EM model of resistor you cannot simulate it. Change the partition rule to circuit and run meshing and EM simulation. After that, create a component of this layout and place this as component this in a new schematic. The component looks like layout with pins at port ends and resistor. Now add the resistor in schematic and simulate S- Parameters.

Don't forget to place pins at the location you are placing resistor. They shouldn't be wrt to GND! Check out this example image I have cropped out from one of my design Observe pins 1,3,4

Pins 1 is wrt gnd which acts as Port 1 where as I place a passive component between port 3 and 4.

Check out this link for procedure to converting layout to component and simulating it. This is example of microstrip filter.
