How do I optimize a model that is split in frequencies?

There was an error rendering this rich post.

I am currently trying to optimize a broadbanded device that requires the use of different solvers and meshes for different parts of the spectrum. So, several meshes and some frequencies computed with MoM, some with MLFMM and some with MLFMM/GO. Computing the low frequencies with MLFMM activated causes crashes/convergence errors and computing the higher frequencies with MoM takes forever and causes RAM errors.

Is there a way to split such an optimization calculation withing postfeko?

Or alternatively is there an established workflow to link such a split model with external optimization tools such as hyperstudy.

Hi Tobias,

Unfortunately, I am not aware of any possibility with OPTFEKO. I cannot say for sure whether it would be doable with HyperStudy. Perhaps @Garima_Singh can comment here?

Best regards,

Hi @tobias_from_edag,

Since, we require further details on the use-case to suggest whether it can be handled in HyperStudy, it would be great if you can either mail the requirement on hwsupport@altair.com or create a support case using Altair One.

Kindly mention the case number as a response here so that we are aware of it.

Many thanks.

Kind Regards

I have talked with Hyperstudy support, and it seems like I will have to manually setup each sub-model in hyperstudy.

Hi @tobias_from_edag,

Thank you for the response.

I have checked the response provided by the FEKO team in the case number CS0763972. However, I would be interested in understanding more on the use-case.

I will create another case particularly for HyperStudy for your requirement to discuss it in detail.

Kind Regards
