I am working on Ka band. So, I am having meshing problem as my object is 42 times the wavelength. How to rectify it?

    Hi Vikas88

     

    What exactly the meshing problem? Too many triangles?

    Please provide more details and attach your model.

    Hello Vikas88,

    I suspect that you are simply running into issues due to the large number of elements, but even if you do mesh the model (and we could provide some suggestions if you provide a better problem description), how are you going to solve it (you will need a very large machine or cluster)? Is the solution not rather to use some of the other features or solution methods in FEKO? If you give us a description of the problem, we can suggest alternatives that reduce the number of required elements (HOBF for MoM or MLFMM if you need a full wave solution or PO, LE-PO, RL-GO, UTD for an asymptotic solution).

    If you are using Student Edition, it has limited resources (such as number of meshes).

    So you can not create infinite meshes.

    If your simulation environment is too big, either you should simulate this in lower frequency, or if you had to simulate it in higher frequency (needs more mesh) you need to buy licence.
