I am getting the following error while simulating the design. Used the waveguide Port.

    Hi Ssachdeva

     

    Please also share the output of the 'Output' window. It should give more clues as to what's going on.

    This is the output of the 'Output Window.

    Hi Ssachdeva

     

    The model requires 29 GByte of RAM. Your output shows that the out-of-core solver was initiated. 

    This could be slow, depending on your hard drive type (faster with SSD, slower with older drives, etc.)

     

    The error further shows that you do not have write permissions on the C:\Temp folder. Check your permissions and also that you have sufficient disk space.

     

    I am not sure what you are trying to do, but note that your wave guide modes at 500 MHz are evanescent. Modes are given in the *.out file. I did not run the whole model. 

    You should also consider to set a local finer mesh size on the wave guide port faces to accurately model the modes. But this would increase the required memory.

     

    Depending on the modes, it may be possible to use electric and/or magnetic symmetry, which would reduce the memory by at least 2 to 4 times.
