增加 LE -PO 法。
大型的mesh单元物理光学法。 吸收grasp 的算法优点。
以后可以进行电大问题的更好运算。
Large element physical optics (LE-PO): The physical optics
solver has been extended to support electrically large
elements with plane-wave based basis functions. This leads to
dramatic reductions in computational cost, in cases where
these elements are applicable, as the element can be very
large in terms of wavelengths (2λ or even more). Typical
applications are RCS, antenna placement and reflector
antenna analysis where the first reflection is dominant.
Shared memory parallelisation: Distributed memory
parallelisation has been available for all phases of the FEKO
solver, allowing the efficient use of cluster, multi-core and
multi-CPU computers. FEKO Suite 6.0 introduces pure or
hybrid shared memory parallelisation based on multithreading
for the MoM and MLFMM solvers. This leads to memory
(MLFMM) and runtime (large MoM) savings on multi-core CPUs
and multi-CPU systems.
Aperture modelling with planar media: FEKO has a dedicated
planar multilayer MoM solver to simulate microstrip
geometries very efficiently. In Suite 6.0, the capability to model
slots in infinite metal surfaces inbetween dielectric layers was
added. Only the slot aperture needs to be meshed, resulting in
large savings of runtime and memory requirement.
GPU acceleration of the MoM solver: Modern GPUs (Graphical
Processing Unit) are now capable of complex parallel
computations and can be used for general-purpose
Frequency dependent material modelling: In the
past, a loop construct in EDITFEKO had to be used
to realise a frequency sweep of a model with
frequency dependent material properties. Models
for variable dielectric properties (e.g. Cole-Cole,
Debye) can now be used to define material
parameters.
Integrated SPICE circuit solver: SPICE circuit
model files can now be incorporated into FEKO
simulations. For example, a complex matching network may be attached to the feed port of an antenna
and simulated together with the antenna. FEKO supports the Berkeley SPICE3f5 syntax.
Extended cable coupling capabilities: FEKO now natively supports a number of cable types and bundle
configurations, for EMC cable coupling analysis (cable irradation only). The cable types supported are
single conductors, coaxial lines, widely spaced multiple conductors, multiple conductors with a shield
and ribbon cables. For shields, the Kley formulas have been implemented, as well as the Schelkunoff
model.
Error estimation: The estimated error distribution in a numerical result can now be viewed in FEKO, to
assist the user in refining the discretisation where it is most needed, minimising computational cost.
FEM-MLFMM hybrid solver: The FEM can now be used together with the MLFMM. This is an ideal
solution for bio-EM analysis of bodies in close proximity to large metallic objects, e.g. a human
phantom inside a vehicle.
Accelerated mono-static RCS calculation with the
MLFMM: FEKO now uses a phase corrected
version of the previous angle’s solution to speed
up the iterative process. This can result in
dramatic runtime savings.
Adaptive Cross Approximation (ACA) acceleration
of the MoM solver is an exciting alternative to the
MLFMM, dramatically improving the computational
efficiency of the MoM. ACA is particularly wellsuited
to areas where the MLFMM is not
applicable, e.g. planar MoM and electrically small
but complex structures.
如果 LE-PO 可以实现多次反射的话,那就好了。
如果不能支持多次反射 感觉改进不是很大啊
如果GO支持散射的话 LE-PO 基本可以用GO代替了
不过GO也不支持多次反射问题 对多反射面天线的处理在FEKO里面太麻烦了
feko 都6.0了,好快啊
go 是支持多次反射的。
但GO 算多反射面天线根本算不准。
何时见到试用版呢
实验室全面升级到feko 6.0了,正在摸索中
PFeko改变挺大的
谈谈Post Feko的初步感受,有点像当时从microsoft office2003转到2007时的感觉,上方大分栏+大图标
整体来说是好用了
小编,分享一下软件吧。
在google可以搜一下啊,可以找到的
请问小编有没有和谐文件啊?我在网上找的现在不支持并行运算,仿真大模型太费时了。
