Description

Technical Field

[0001] This invention relates to the field of electromagnetic simulation technology, and in particular to a method for importing far-field data from HFSS software into CST / FEKO software. Background Technology

[0002] Electromagnetic simulation plays a crucial role in the research and development of electronic equipment. Among them, HFSS, CST, and FEKO software are some widely used electromagnetic simulation software programs.

[0003] Because HFSS and CST / FEKO software are developed by different companies, there is no common interface file between the two. However, in practical applications, developers need to import far-field simulation results obtained from one software into the other to complete subsequent simulation work.

[0004] Existing software interfaces cannot import far-field simulation results from HFSS into CST / FEKO software. Furthermore, each import / export process requires manual operation, which is time-consuming, labor-intensive, and inefficient. Summary of the Invention

[0005] In view of this, the present invention proposes a method for importing far-field data from HFSS software into CST / FEKO software. This method can import far-field simulation results from HFSS into CST / FEKO, and is characterized by speed and convenience.

[0010] Step 3: Convert the acquired far-field data file into a data storage format to form intermediate format data;

[0011] Step 4: Convert the intermediate format data into a far-field data file that conforms to the CST software format.

[0012] Furthermore, the far-field data file corresponding to the simulation project in the HFSS software has the suffix ffd, and the far-field data file conforming to the CST software format has the suffix ffs.

[0017] Extract the electromagnetic information in spherical coordinates corresponding to the frequency information from the far-field data file, and write it into the corresponding spherical coordinates in the intermediate format data.

[0018] Furthermore, step 4 is specifically implemented as follows:

[0019] The frequency information in the intermediate format data is written into a far-field data file that conforms to the CST software format in one go;

[0020] The spherical coordinate information corresponding to each frequency information, as well as the electromagnetic information under each set of spherical coordinate information, are sequentially written into a far-field data file conforming to the CST software format.

[0026] Furthermore, the far-field data files corresponding to simulation projects in HFSS software have the suffix ffd, while the far-field data files conforming to the FEKO software format have the suffix ffs.

[0027] Furthermore, the data storage format includes frequency information, a set of spherical coordinate information corresponding to each frequency information, and electromagnetic information corresponding to each set of spherical coordinate information; wherein, the spherical coordinate information is represented as (phi, theta), where phi represents the angle between the projection of the coordinate point on the XOY plane and the X-axis, and theta represents the angle between the coordinate point and the Z-axis; the electromagnetic information consists of four data, namely the real part and the imaginary part of the electric field components along the phi and theta directions.

[0028] Furthermore, step 3 is performed as follows:

[0029] Frequency information is extracted from the far-field data file and written into intermediate format data;

[0030] Extract the spherical coordinate information corresponding to the frequency information from the far-field data file and write it into the frequency information corresponding to the intermediate format data.

[0031] Extract the electromagnetic information in spherical coordinates corresponding to the frequency information from the far-field data file, and write it into the corresponding spherical coordinates in the intermediate format data.
