why my co-simulation show error in ADS?

Hi friends,
I want to co-simulate power divider when i create layout component,it shows error.Anyone can help me?

Your file name(k=1_splitter_optimization_complete_1) for the layout is not a good one. Change to a short one such as "k111" should then be ok.

Thanks,Kayaoo.As your mention,i fixed it.But one case show as following when i ran momentum.

How i can solve it?

I have no idea as my ADS2005 does not report such a warning. However I don't think it will be a problem if you do not use "reference offset".

Oh...is it nothing with getting an accurate result if not use the "reference offset".?

Try with enabling thick conductor i.e under mesh control enable the horizontal currents.
