Hi everyone,
I’ve created a power divider on layout, when I use the component from the library on the schematic and do the simulation, I get an error message.
I don't know how to solve it.
Can anybody help me?
Thanks for replying.

How do I do it?
Could you describe the steps, please?
Thanks a lot, Volker!

Do you know why?

Does the Momentum simulation finish properly when started manually?

You might also consider using defined size for the ground pins:

I am doing the power divider with CPW transmission line. You can see how I define the ports

Yes, and what I see is wrong. The ground pins must be at the edge near the signal conductor, not so far away as you have placed them. The ground current will flow at the edge of the conductor, at the gap. The position where you have placed the pin inserts a large extra path length.
For the error message, I think that is related to placement of ground pins (multiple pins on same edge on output side). You should contact Keysight support for help.

Do you say than the other ports are badly located too?
About the error message, I've tried to split the conductor in 2 parts, each one with a ground port, like the image but I get the same error.

From more than 15 years experience as an EM simulation expert, yes, all ports placements look wrong to me.
