We have one 4CPUs server with AMD Opteron 61xx (2x6 cores). But this is a NUMA (Non Uniform Memory Access) machine.
What is the best way, then OS ?, to optimize the management of this kind of machine ? I can read somethings Windows Server 2012 on the WEB...
You need to create one or more monitor E-field (by solve menu), and you can choose frequency in this.
After the simulation, you will find the 3D results : adjust the view parameters to visualize properly the fields (you can extract severals 2D plane of).
Yes. It is not easy to control the pattern without array principle antenna !
The last solution is to defocus the dipole-feed behind one reflector like one parabola...
but I am not sure that is the best solution.
I don't know sufficiently your specifications to help you correctly.
It depends of your structure, is it resonant, is it an antenna... generaly, if you decrease the accuracy value, you must be carefull of your frequency range :
you will have to decrease it.
About the simulation time (in help CST MWS) :
Now, could you describe your backround and boundary conditions of simulation HFFS ?
How do you made your exitation ? with coaxial ports shielded or not...
I think that you need to check the independance of your antenna.
I fear a problem similar to quantum mechanic ; it is not a joke !
The system under test (your RFID antenna) is disturbed by the the measurement system... I believe.
This test seems very difficult to give a good measurement.
Could you simulate your RFID antenna with 3D-EM software ?
Re: [reflectarray antenna]---> cross polarization simulation using HFSS or CST
1) Create (in solve menu) Farfield Monitor(s) @ n frequency
3) The results will are in the farfield directory -> choose the good representation (ludwig 3 linear or circular) by click right ...
