How do you mesh on a fastcap .qui file if you are not using PATRAN, and puting your own coordinates. This is as if putting wires on a pcb board and measuring the capacitance between the wires. Because I keep getting the error message: Warning - capacitance matrix has non-negative off-diagonals?

You have to provide an already meshed file to FastCap2. FastCap2 has no meshing capabilities of its own.

So can you mesh a 3D conductor and a 3D dielectric interface using PATRAN files?

Yes that's one option. The other one is to have the mesh generated in the FastCap2 format by some intermediate conversion or directly by some script.

You can find some examples in the 'Samples' directory in FastCap2 installation path
