[已解决]怎么才能看Ray 射线的图？

设置好了po 计算，想看看射线图。可是在postfeko里怎么都看不到。 !."%M^J  
我看手册说要选择solution setting 里面的export ray file for post-processing，可是无论怎么设置都没有成功过。 <:kTTye|  
还试过在editfeko里面设置UT选项卡保存ray file一项，还是没有作用， ]$XBd{\D{

UTD/GO rays page \g6 #MNW  
This page controls the visibility of UTD and GO rays. Note that the rays are fz?Wr: I  
not stored by default as the *.ray output file can quickly become very large — F]&J%i F[  
it must be explicitly requested on the Solution settings dialog (see section 6.10) o? xR[N-J  
in CADFEKO or the UT card (see section 13.45) in EDITFEKO. 0&L0j$&h  
The check boxes for Ray lines, Ray group number, Ray numbers and Intersection point eiSO7cGy  
determine the level of information displayed for each ray. The Select tab is used to select
PG~m-W+  
specific rays. Each ray group includes all rays that start and end at the same point. Ray Q,qylL  
type limits the display to certain types of rays. Finally the Field type facilitates selecting Ckl]fy@D}  
rays obtained during specific calculations — it is, for example, possible to hide all rays zvs 2j"lb  
calculated when determining the coupling between the UTD and MoM regions. The Far yI)fu^  
field crop slide bar can be used to restrict far field points to within the geometry display. @LMV?  
POSTFEKO includes the functionality to display the relative magnitude of the contributions <x;[ H%  
due to the different UTD and GO rays. 9(

With this command the parameters for the Uniform geometric theory of diffraction (UTD) 2Lu{@*  
for polygonal plates and Geometrical optics for dielectrics (GO) are defined. _G8y9!J  
When no UT card is used, the following default values apply: E|A_|FS&%  
• Max no. of ray interactions: 3. r-"`Abev  
• Write debug information to *.dbg: unchecked. =<W[dV=W  
• Export UTD ray data for later viewing: unchecked. xfV2/A#h  
• Select ray contributions includes. #FDu4xi  
– GO (direct and reflected rays, shadowing). )mZy>45  
– Edge and wedge diffracted rays. {ZYCnS&?CL  
– Corner diffraction terms. 4hr+GO@o(  
Increasing the type and number of ray interactions increases accuracy but computation f'yd{ihFp  
time as well. The user should therefore make a compromise between the number of ray `3s-%>  
interactions and the ray contributions. Choices made in this card should be made on eMd1%/[  
physical considerations to get optimal use from the UTD formulation. =Q0)t_z_  
The following restrictions apply for the hybrid MoM/UTD: Mn{Rg
>X  
• No dielectric bodies or dielectric ground. ]8cX#N,M  
• Only perfectly conducting flat polygonal plates or a single cylinder allowed in the owVUL~  
UTD region. ['YRY B  
• No UTD and PO at the same time.

谢谢，我回去尝试一下，是不是op ， utd,都可以看ray的？ Q1?09  
我也选了solusion set里面那个东东 export ray to postprocess,但是decouple mom我是选择的，难道必须和mom耦合计算才能看ray吗？

可產生RAY..你可以試玩一下....  但我之前沒做過這方面的應用.. vv"_u=H

很好的帖子 学习了 谢谢

这个好玩，从来没看过，只是不知道PO明明不是基于射线法为什么要叫“ray tracing”
