Reply To: Both Frequency and Time domain(transient) simulation in HFSS

[Jason.k]

Hello Sghose, 

When you select "Transient Simulation" as the solution type in HFSS, it is designed to affect the available options for the setup, including the Excitation tab.

The Transient solution type has specific requirements and settings that may not be compatible with "Magnetic Biasing." This is why you might have noticed that "Magnetic Biasing" was automatically removed from the "Excitation" tab upon selecting "Transient Simulation." 

As we can see from the error, such material is not supported with the specified solution type in HFSS. Since that HFSS Transient solver has specific capabilities, this might require further assistance or coupling with other Ansys Software. Also, since we are referring to a complex -non straighforward- problem, for this type of issues, please, feel free to contact us through Ansys Technical Support by raising a Case. 

Regarding on how to design magnetic material using HFSS: This procedure involves specifying material characteristics for your structure. According to the Ansys HFSS documentation, when creating a ferrite material, you need to define the net internal field that biases the ferrite by assigning a magnetic bias source. This bias field aligns the magnetic dipoles in the ferrite, producing a non-zero magnetic moment. You can select the 3D ferrite object to which you want to assign the magnetic bias source and specify whether the applied bias field is uniform or non-uniform. For more detailed info please, refer to our documentation and search for "Assigning Magnetic Bias Sources"

As mentioned previously, please, do not hesitate to contact Ansys Technical Support for this type of problems in case you need further & detailed assistance.

Kind regards, 
Jason.
