When I open the Electronic Desktop, Twin Builder auto opens

lumierelumiere Member Posts: 2

I installed the electromagnetic package from my university. Programs like Electronics desktop, siwave, twin builder, and more were installed. I am having trouble finding HFSS though. I have looked through the download directory and am not sure what to do. Can some one help me find HFSS?

    HFSS is accessible through Electronics Desktop.

    Open Electronics Desktop, then choose file and open the HFSS file that you would like to open.

    Best Regards,

    Hello, thank you for replying.

    I am trying to insert a new HFSS project not open a pre-existing file. 

    Is there a way to insert a new HFSS design on the electronics desktop? The only option I am seeing is insert a new twin builder design.


    Thank you

    In ANSYS EDT / Simplorer GUI --> Tools --> Options --> General Options --> Desktop Configuration -->

    Set Targeted Configuration, Custom Menu, Set Schematic Environment. All of the above may be set to Simplorer, Change to other relevant option (

    Also, New Project Options. When creating a new project. Insert a design on type: may also be set to Simplorer, change it to the desired value from the drop down or choose "Don't insert a design"

    For details please refer ANSYS EDT Documentation > Working with ANSYS Electronics Desktop Projects > Setting Options > Setting General Options General Options: Desktop Configuration. Close "Simplorer" & Start ANSYS EDT (Maxwell).

    Please, I have related issue.

    I have designed my work using Ansys Electronic Desktop HFSS but during simulation my system crashed. After restart, Ansys displayed messages as if I just installed it with new directories. Since then, I could not open my work again with error: "THIS IS NOT ANSOFT PROJECT". Please, how can I handle this?

    This is a different issue. Please create a new thread for your own and include an image of the screenshot of the error, inline with text (don't put in attachment)

    I'm locking this topic.
