Re: Download Cst Microwave Studio Full Crack
Kjersti Mootz
Hi everybody,
I'm new to CST microwave studio. Just finish constructed a structure ofan L-probe patch antenna (from IEEE paper) and just run the simulationby transient time solver, the curve of the return loss(S11) againstfrequency that i get is different from what showing on the IEEE paper,so is it the boundary condition setting will affect the simulationresults? And actually what is the function of setting the boundarycondition?
During the simulation, a warning message "some PEC material is touchingthe boundary" was show. After change the boundary condition setting to"open(add space)" then the warning will eliminate when run again thesimulation. But the s11 curve still different from the "actual" results.
Anybody can help?
Any comments will be appreciate.
Thanks.
Dassault Systmes Simulia Corp. is a computer-aided engineering (CAE) vendor. Formerly known as Abaqus Inc. and previously Hibbitt, Karlsson & Sorensen, Inc., (HKS), the company was founded in 1978 by David Hibbitt, Bengt Karlsson and Paul Sorensen, and has its headquarters in Providence, Rhode Island.
In October 2005, Dassault Systmes acquired Abaqus, Inc.[1] and announced Simulia, the brand encompassing all DS simulation solutions, including Abaqus and Catia Analysis applications. Dassault Systmes Simulia Corp. is the legal entity that encompasses the Simulia brand of Dassault Systmes.
The Abaqus suite consists of three core products: Abaqus/Standard, Abaqus/Explicit and Abaqus/CAE (Complete Abaqus Environment). In addition to this, recent versions of Abaqus (6.10 onwards) also contain Abaqus/CFD for computational fluid dynamic simulations.[2] Each of these packages offers additional, optional modules that address specialized capabilities required by some customers.
Abaqus/Standard provides analysis technology to solve traditional implicit finite element analysis, including static, dynamic, and thermal analyses, all powered with a range of contact and nonlinear[disambiguation needed] material options. Abaqus/Standard also offers additional add-on products and interfaces, which cater to functionalities like design sensitivity analysis, offshore engineering, and integration with third-party software, such as plastic injection molding analysis tools.
Abaqus/Explicit specializes in analysis technology tailored for transient dynamics and quasi-static analyses, employing explicit time integration methods. This approach proves suitable for various applications, including drop tests, crushing scenarios, and manufacturing processes.
Abaqus/CFD provides advanced computational fluid dynamics capabilities with support for pre- and post-processing provided in Abaqus/CAE. These simulation capabilities address a range of nonlinear coupled fluid-thermal and fluid-structural problems.
In addition to the development of the pre-existing Abaqus portfolio, DS has also developed Simulia V5 and V6 product suites which seeks to combine the modelling and simulations aspect into one tool.[3]
CST Studio Suite is a computational electromagnetics tool developed by Dassault Systmes Simulia. It contains several different simulation methods, including the finite integration technique (FIT), finite element method (FEM), transmission line matrix (TLM), multilevel fast multipole method (MLFMM) and particle-in-cell (PIC), as well as multiphysics solvers for other domains of physics with links to electromagnetics.[4][5][6]
The predecessor to CST Studio Suite, MAFIA [de] ("solving Maxwell's equations with the Finite Integration Algorithm"), was sold by CST, a university spin-off from TU Darmstadt founded in 1992 to commercialize the FIT method originally invented in 1977 by Thomas Weiland.[7] Although the software was initially developed for particle accelerator laboratories, it found application in microwave engineering, and so FIT was implemented in CST Microwave Studio (CST MWS) in 1998, which became CST Studio Suite in 2005.[8][7] CST was acquired by Dassault Systmes in 2016, and since then CST Studio Suite has been a product of Simulia.[9]
The time domain FIT method uses a proprietary meshing technique called perfect boundary approximation (PBA) to represent curved surfaces in a hexahedral mesh, and there is also a frequency domain FEM solver.[10] Other methods include the MLFMM and shooting boundary ray EM solvers. There are also multiphysics solvers such as PIC, wakefield, thermal and structural mechanics.[11]
As an electromagnetic design tool, CST Studio Suite is chiefly used in industries such as telecommunications, defense, automotive, aerospace, electronics and medical equipment.[14] One application of CST Studio Suite is the design and placement of antennas and other radio-frequency components.[15] The antenna systems on the BepiColombo Mercury Planetary Orbiter were developed using CST Studio Suite to investigate their radiation pattern and possible electromagnetic interference.[16]
Every flower presses differently, some keep their color and others change. Some are more difficult and others are quite simple. Every FruitFlowers arrangement from Edible features seasonal flowers so they all vary slightly to make sure the blooms are at their finest and freshest when delivered! The flowers and greenery included in mine pressed beautifully!
You will notice that not all colors stay the same once the flowers are dried. Yellow holds its hue the best, whereas hot pinks turned more purple, and pastel flowers lost a bit of their color. The same goes for greenery, some greenery, like myrtle and the leaves I pulled from rose stems, held their color, but leaves like eucalyptus turned more olive.
1. Alongside a photo or card: Try using the frame as more of a shadow box or collage to preserve a memory, occasion, milestone or season of life. Include a photo, invitation, card or other piece of memorabilia alongside your flowers! Place the photo in the center of the frame, or in one of the corners, and have a few blooms overlap it to tie everything together.
3. Make it a bouquet: If you like the look of pressed flowers with the stems still on, try arranging them so they look like a dried bouquet inside the frame. Gather all the stems at the bottom as you lay your various flowers inside, and let them spread out towards the top to form a bouquet shape.
A great gift idea would be to gift a beautiful frame alongside a flower bouquet, like the gorgeous FruitFlowers below to give the recipient an easy boost towards preserving their flowers for years to come!
Maybe you can try adjusting some of these variables and see if you get better results. For example, you can use thinner or more absorbent paper towels, cut the stems shorter, or reduce the microwave time. You can also check on the flowers every 30 seconds to see how they are doing.

In hyperthermia treatment for cancer, the antenna used as hyperthermia applicator needs to be designed carefully in order to heat the cancer cell without affecting the healthy cell. Unfortunately, as different antenna design produces different radiation pattern, it will lead to different heating distribution values. With these values, the time duration of the exposure for the cancer cell will also be different. In this research, the capability of a dipole antenna as hyperthermia applicator has been analyzed. The analysis has been done using simulation model in CST microwave simulation software based on FDTD technique. The result shows that the dipole antenna is deemed to be used as hyperthermia applicator. The heating pattern from the dipole antenna based on SAR distribution pattern shows that the focus area of the human tissues model, that has been designed using water bolus model has high Specific Absorption Rate (SAR) value compare to the surrounding area.
The specific absorption rate, SAR is designed specifically for the measurement of EM wave radiation absorption in tissues and represents the amount of energy or power deposition per unit normal human tissue. As defined in equation (1), the value of the averaged local SAR was calculated as:
where Ε is the electric field strength (V/m), σe is the effective conductivity (S/m) and ρ is the mass density of the tissue (kg/m3).11 In order to meet basic SAR restriction for general public exposure that use averaged method in IEEE/IEC 62704-1, three averaging mass or point SAR for SAR calculation such as 1g, 10g and point SAR has been introduced. Nonetheless, this research study only considers SAR calculation for 1g. For the most part, the averaged SAR calculation for 1g is less than 1.6W/kg as stated in IEEE Standard for safety levels for power delivered by the antenna that had to be altered.
The length of the dipole antenna that is equal to a half-wavelength at the frequency of operation defines in a half-wave term. Besides, the dipole antenna is the basis for most antenna designs which is a balanced component with equal but opposite voltages and currents applied at its two terminals through transmission line.
The half-wave dipole antenna has been designed at a resonant frequency 2.45GHz. The proposed design parameters of the half-wave dipole antenna have been simulated by using the CST Microwave Studio 2019 software. The design of the dipole antenna used in this study is as shown in Figure 1. The summary of the dipole antenna dimension designed in this study can be referred in Table 1. In order to design a hyperthermia applicator simulation model, the design dipole antenna of this research needs to be extended by adding a water bolus model in the simulation design. The aims of the simulation which is using the water bolus model as a material in the simulation techniques is to measure the SAR in the water bolus model. By this simulation, the heating value of the design antenna as hyperthermia applicator can be determined. The time exposure of the applicator could also be estimated based on this simulation. The design hyperthermia applicator model in this research is as shown in Figure 2 & Figure 3. In this research, the half-wave dipole antenna as hyperthermia applicator simulation model is designed by using the perfect electric conductor (PEC) and a water bolus model in cubic shape. The dimension of the normal water bolus model is 100mm x 100mm x 100mm for thick, high and width respectively. The epsilon value (permittivity) of the water is 78. The dynamic viscosity of the water bolus model is 1. Besides, it can be seen in Figure 3 that the electric conductivity of the water bolus model is 1.59S/m. The density of the normal water is 1000 kg/m3 while the thermal conductivity is 0.6 W/K/m. Furthermore, the heat capacity of the water bolus model is 4.2 kJ/k/kg while the diffusivity of the model is 0.000000142857m2/s.
