### problem with multibody simulation (capacitance)

Posted:

I tried a new strategy generating a mesh file with autodesk nastran(student version) case.nas then I convert with gmesh in case.unv and then inporto in Elmer.

things seem to be going better but I have problems because the two central bodies pipe+flow and the low potential electrode +cover (bodies on the right) do not communicate with the rest remaining isolated

the part being studied is exactly that, so that's a problem.

Someone knows how to help me.

thanks in advance
