Problem with HFSS simulation time of center-driven dipole

[waltzsu]

I am simulating a center-driven dipole, 1m long. If the radius is larger than 2mm, the running time and simulation results are both acceptable. However, if the radius is 1mm, after a whole night, it is still running!, It is terrible and ridiculous.

Re: HFSS is terrible!

try to use 75 ohm feed and a balun


try to make it lamda/8 in mm thick check the resistivity isnt set too high

HFSS is terrible!

the cylinder is too slim, the aspect ratio of the mesh grid is too large. you'd better draw a prism instead of cylinder.

Re: HFSS is terrible!

This sounds to me like an error in the initial mesh.
Give me your .hfss-file, so I can look at it.
