Using HFSS export on grid

I've modelated a structure with a single trace with port and rlc. And I'm trying to find E-field in different poinds around the trace, using calculators export to grid function. In the report it posts "No Solution" in almost all points. Field overlay shows "points" of field.
What can be wrong with it? How can I find a value of the field in the definite points?

Thanks for help in advance.
