I have designed a cavity backed antenna.when i assigned copper to the cavity .i found the following errors HFSSDesign1 (DrivenTerminal) solving inside a solid with high conductivity may require a large mesh (8:21:06 PM Sep 15, 2016) Adaptive solution setup, process hf3d error: Failed to solve the port 1 due to lack of
To export from HFSS After solving in HFSS, right click Analysis-> setup. select Matrix data. Check the display all frequencies box and the S matrix box then click Export Matrix Data. name the file and choose the location. To import to Designer Project->Add Model->add Nport Model. select Import data under Mode. Browse to the file location and c
I am quite new to the HFSS software and encountered this problem today. I was trying to design a birdcage coil for MRI applications. However, after I setup the model and started the analysis, the software couldn't compute the problem. The error message said: Adaptive solution setup, process hf3d error: Failure in solving matrix. I tried to (...)
are you just solving for the 2D cross section or for a finite length of fiber (which can be determined from 2D cross section assuming invariant geometry in propagation direction) I have set these up successfully and have reproduced n_eff vs V frequency plots for step core fibers that correlate references. Yours should have similar setup concerns
In order for HFSS to utilize all the cores, you must purchase the MP or HPC license from ANSYS. HFSS by default will only access one core for solving. Also, depending upon your setup, HFSS solver may be trying to grab more than 1.4GB though you are unaware of it. For example, if you enable the iterative solver it will be very efficient on RAM an
Hi friends, Please discuss the various techniques to solve setup violations? Please elaborate on why and when we use each technique. How to take care of hold violation at the same time? Thanks in advance, Sowmya
If waveports and lumped ports are setup correctly you should get exactly the same answer - if you are only solving for one mode and renormalising to 50 ohms anyway. If you use a 50 ohm lumped port you should get the same answers. The main difference is that a lumped port needs to go on an object that is literally drawn between your conductor and yo
HI, I know setup and holdtime. I need some examples to calculate this.... I always find some difficulty in solving this timing issues. Pls help me
Could you give some hints about solving Laplace equation using method of moments for 2 infinite cylinders ?????????? :cry::cry::cry:
there are specific tool in ise for solving the setup/hold timing problem, however at the most time you need not take care of that.
Hi, I know that buffering will help in solving the slew violations, but there should be limit on number of buffers added. what is the limit? what is the relation between the slew and the number of buffers added? Please help. Thanks, Sowmya.
Self study is the better way to understand this problem! Just draw a flipflop with gates and assume some delays for each gate and try solving this by changing inputs at different time intervals. Then you can easily understand why u require a stable signal in between setup n hold time !!
You must activate "Solve Inside" at the properties of the Helix_trace. But solving inside such a huge metal object may overstrain your computer. Perhaps you should try to excite with a current. You also have to define the substrate's boundary. Or, better: Add a box to your setup, filled with air or vacuum, which is as large as the substrate bu
hi Suppose that im in my design one of the flops is giving setup time violation. What are the ways in which i can solve it?
