Dear Eman,

In my view, its better you you model your RF structure in HFSS and CST separately...then compare the results...instead of importing/exporting one from /to each other.

My Ph D student tried it.

Hi

You can use export function in HFSS with .STL or .SAT.

CST can read them. You should know that you cannot change parameters in CST if it is imported file from HFSS.

I agree with Vedvyas sir. Even if you import any design, you will not be able to understand properly the design by its parts or sections as it was in the root software. Also you can not change the dimensions. 

Dear Eman,

You can able to import DXF files from CST into HFSS.

you have to select all parts in the navigation tree then choose in modeling tab export to sat but choose version between 18:20 it is near the name file. (because hfss work with version older then cst). or if you have the new version export to parasolid x_t. then you can import it in hfss look for import. 

Kindly Refer this Link.

But Consider Dr.VedVyas Sir Suggestions as you import any design, you will not be able to understand properly the design by its parts or sections as it was in the root software.

Agreed with Dr Vedvyas Sir...the renowned teacher of Electromagnetics and antennas

Thank you all for taking the time to help!

i only got one issue , i downloaded the CST studio suite student version but itis very limited .i checked a couple of videos to understand how to start the simulation because i am quite new with this simulation program. When i tried to start the simulation i keep getting this message that the model mesh size is large compared to the allowed mesh size in CST student version ( i.e. 30000)

could someone provide me with a link to download full version of the program ??

i wan to simulate an antenna for bio medical app. and i wan to validate this design by attaining results such as SAR , temperature distribution, coagulated volume s parameter radiation pattern

could someone help me please i am really stuck with the simulation...

Really appreciated!!

Regards.

Hi,

You need to use CST Microwave and CST MultiPysics to see the temperature.

You can read the papers I have published:

"Characterization of Corroded Reinforced Steel Bars by Active Microwave Thermography"

"Application of active microwave thermography to inspection of carbon fiber reinforced composites"

"Application of active microwave thermography to delamination detection"

I did the same modeling, but for Structural Health Monitoring.
