PS: I do not know what i have done wrong.
I dont know what " an invalid state" is?
Simulation aborted due to invalid state.
maybe you don't feed your blade monopole antenna, could you send me your project?
But, if you send me your project, I could help you!!!
The message “Invalid State,… Exit Code 24” is just an internal coding for bugs identification.
We are going to update the silver version next days with the bug solved. I recommend you to wait to this new version that also will be more robust and able to handle more MoM subdomains and surfaces.
A quick question.....even if I add a metal in ground plane in the model, will I still fail to execute the simulation because there is a bug in the present Release of the tool?
Meaning, no matter what I simulate, even the example u hot link me to, I will still have failure?
I also note for coaxial feed, the "setup parameters " box does not really tell the user where the connection is made to the geometry surface in the mesh tet. This seems inaccurate. The user does not know where the reference placement is in the model.
if a proper ground plane is added, how much space should there be between the Groundplane and the Blade antenna?
Should there be a gap? Or should the surface of the feed point touch the Groundplane?
Yes, there was a bug with some Coaxial Feed primitives (such as the Blade one) in the present Silver (6.2.7) version, even considering a metal as ground plane. It is already solved in new (6.2.8) version that will be available as soon as we finish the quality tests.
The bug may appear in some Coaxial Feed primitive, with and without ground plane.
The user can edit both the voltage and impedance given a Feeding point defined by two surfaces. With this information, the feeding is automatically carried out.
When one of the surfaces is shown as “Auto” (as in the Blade Primitive Antenna), the voltage is automatically inserted in the surfaces connected to the antenna that will be typically its ground plane (See attachment “Fig. 1”).
if a proper ground plane is added, how much space should there be between the Groundplane and the Blade antenna? Should there be a gap? Or should the surface of the feed point touch the Groundplane?
The ground plane surface and the antenna must be physically connected, that is, without gap between them, as shown in “Fig 1”.
We appreciate your feedback and comments and they will be taken into account for improving the user experience.
Thank you for clarifying the details needed for a successful Simitation. Without the detail of proper use of Ground plane, it would be useless result!
There is a selection box in simulation that asks "include groundplane". Is this an Infinite groundplane?
I ask because this Plane option does not have any visibility in the GUI.
We will update the user guides and GUI descriptions to clarify those questions.
You are right, the "include ground plane" option enables an infinite ground plane that is usually considered for RCS simulations. For coaxial feed antennas, it doesn't provide the effect of a physicall groud plane where the antenna is placed on, as the one that I mentioned in the previous message. It also will be better explained in the user guides for avoiding confusions.
