Re: How does one open a support ticket for Altair products?
I am also interested in the answer to this question.
I was able to contact Siemens support and submitted a ticket.
I had to use one of the siteids in the directions, something like 00001234.
The SLC setinit does not provide a siteid.
It immediately told me that it can take up to 5 days to get permission before
They can respond to my ticket.
After four days, Siemens responded that the support group only deals
with online issues. Siemens provided a link for a ticket.
I created another userid and password and submitted the ticket.
It's been three days and I haven't heard anything.
I don't think Siemens understands how their products can be subservient to SLC solutions.
SOAPBOX ON
Monarch, Rapidminer, Openradioss and all those other Siemen products that have a CLI or support ODBC can just be drop drowns from the slc. I think a lot of users would prefer less mouse surfing and a universal interface with the slc?

Re: Monarch Classic 2025 keeps resetting my field lengths.
When I have time I can try to put together a small sample file with the sensitive information masked, and if that still produces the same issue I can send you that.
Re: How to check active reflection coefficient for all ports individually for the array antenna?
You are doing great! Your long explanation helped me to find out which tab in Postfeko is giving me the exact result for the active port. Its so helpful!
Re: How to check active reflection coefficient for all ports individually for the array antenna?
Glad I could help! I apologize for the long talk, I had a misunderstanding with what your desired results were.
Re: How to check active reflection coefficient for all ports individually for the array antenna?
So, for the SParameterConfiguration, the Active button just means it will be considered as a transmitter in the simulation. This means it will consider 4 instances where each port will be excited and the others terminated.
Consider I have a two port system. If I have both ports active you will have for results S11, S21, S12, and S22. This can be compared by two StandardConfigurations, one having VoltageSource1 excited and Port 2 terminated, the other having VoltageSource2 excited and Port 1 terminated.
Say now I only have port 1 active, then you will only have results of S11 and S21. Having port 2 Active not selected doesn't compute S12 or S22. In this case, this is comparable to only having one StandardConfiguration where VoltageSource1 on Port1 is excited and Port 2 is terminated.
If you are interested in S-Parameters, then the SParameterConfiguration I would recommend to use for your analysis. However, if you want all ports excited at the exact same time, then this isn't an S-Parameter analysis and I would recommend to use your StandardConfiguration where all sources are applied to all ports.
I hope this helps!
Re: How to check active reflection coefficient for all ports individually for the array antenna?
No problem at all!
I think with your uncertainty I may also be confused. The S-Parameters such as S11 is determined by exciting port 1 and terminating all other ports. So, with this in mind, the SParameterConfiguration does this as well as the StandardConfiguration_VoltageSource1 as there is only one source and the other ports are terminated to ground.
In the case of the reflection from VoltageSource1 with all other ports being excited by another voltage source, then this isn't a true S11 result. The results are still what you observe, but I don't think it could compare against an SParameterConfiguration because it is a different scenario altogether.
So, if you do just need the reflection for VoltageSource1 with all other ports being excited by their own source, then you only have that one StandardConfiguration to use.
I hope this description helps, please let me know if I can clarify anything.
Re: How to check active reflection coefficient for all ports individually for the array antenna?
@sswh2 Here are files for a quick simulation comparing results. In the .cfx file, you can see six configurations. One configuration is the S-Parameter configuration where all ports are active, this will get results for S11-S44. There are four configurations named with the prefix of _VoltageSource1 to _VoltageSource4, these provide the individual excitations and port terminations to obtain S11-S44. Lastly, there is the StandardConfiguration that includes all ports being excited at the same time.
From the results, you can see from the individual excitation to the S-Parameter configuration, the results align (within a couple dB at higher frequencies):
Now comparing the configuration where only VoltageSource1 is excited, the S-Parameter config S11, and the VoltageSource1 where all ports are excited, you can see the first two align but the last does not due to not being a true S-Parameter analysis:
Please let me know if you have any questions or issues with the files.
Re: Userinput "German floating numbers"
Hi @Pkeks ,
From the Simcenter Motionview side, there is no option to input floating point numbers in the german format type "0,2" instead of the english "0.2". If you are trying to import data that is in german format. I would suggest to create a script (or use your companies AI tool) to go through the data and convert to english format.
Best,
Christopher Fadanelli

Please give me some time to run the simulation, it is taking a while (I have lowered the frequency increment to 10 just for purpose of explanation.)
Re: How can I reset my Altair Student License after my old PC was formatted (New HostID)?
Hi @Stefgio
Your license key has been deactivated in Altair One, and you can now reactivate your student license using the same key.
Kindly note, The Altair Free Student Edition license is valid for use on only one device, it cannot be shared or activated on multiple machines at the same time AND Deactivation and reactivation feature is only if a computer breaks down or reformatted and is only allowed a few times per user preprogrammed into the system.
You can deactivate the license from one machine and reactivate in another by yourself if you have access to both machines as per –
