    Problems regarding Field Solutions in HFSS

    hello

    receiving messages like
    magE becomes invalid due to no available solution......what does it mean?
    and i how to solve this issue what to do?

    Go to analysis -> Add solution setup and add your solution.

    You have to let the software know at what freq (for example) you want to analyze and so on.
    then, you can look at your setup (he will be created after you add solution setup) and make freq sweep or whatever u may need.

    Without adding proper solution frequency in analysis it give that error. By defining the solution frequency it starts meshing and analyze your model. So go to analysis in project manager in analysis add the solution frequency of interest.

    Re: Problems regarding Field Solutions in HFSS

    Always keep one very important point in the mind while using softwares like CST or HFSS, you must be very clear what you are doing and you must have very clear idea what you are designing so that you could have a guess of frequency as these softwares define everything with reference to the solution frequency so if you make a very wired guess of frequency then all will be invalid starting from mesh to the solution. To guess about the frequency it is not that difficult as well as frequency is directly dependent on the size of components and you can have idea that what can be the solution frequency

    ok but sometimes we also uses same frequrncy solutions for different models so what do you think there are any rigid values for frequency solution that will be used for different models like what solution frequency will be used for antenna what for split ring structures and so on.

    Re: Problems regarding Field Solutions in HFSS

    Look it in this way
    HFSS or CST take ask user to enter solution frequency
    And as per entered frequency it will define the mesh.
    Then it will solve the model.
    Solution will not converge or will end up producing completely wired results
    Since model is to resonate at lets say X frequency and you are trying to solve is with Y frequency what you expect in solution
    Keep this very basic point about the working of HFSS or CST
    First of all is discrtize all the solution space which is called mesh
    Then it solve all the model mathematically so do not confuse it with the situation in lab that you are testing something real with some real equipment. Here all involved is mathematics
