Running a Bulk Simulation

AN-SOF can import a sequence of input files to obtain a corresponding sequence of output files, without user intervention in the middle of the process. The input files must be in NEC format and have .nec extension. The NEC commands supported are described in Importing Wires >.

The output data include power budget or RCS, input impedances, far field, and near fields in CSV format. An individual AN-SOF project is generated (.emm and .wre files) for each NEC input file, so each project can be opened separately after the bulk simulation is finished.

To run a bulk simulation, go to main menu > Run > Run Bulk Simulation. A message will appear asking if you want to save the changes in the current project, since the bulk simulation requires closing the project that is currently open. Then, a dialog box will be displayed where a directory and the input .nec files can be selected. After selecting the desired files and clicking on the Open button, the bulk simulation will begin. The input files will be imported and computed one after another.

As an example, for a given input file called “”, the following files will be generated:

Files of the AN-SOF project

InputFile.emm > main file of the project (it can be opened with AN-SOF)

InputFile.wre > geometry data (wires, segments, connections)

InputFile.txt > comments

InputFile.cur > current distribution

InputFile.pwr > input and radiated powers, directivity, gain, etc.

InputFile.the > Theta component of the far field

InputFile.phi > Phi component of the far field

InputFile.nef > near electric field

InputFile.nhf > near magnetic field

Output CSV Files with Results

InputFile_PowerBudget.csv > input and radiated power, efficiency, gain, etc.

InputFile_Zin.csv > input impedances

InputFile_FarFieldX.csv > E-theta and E-phi far field components

InputFile_EFieldX.csv > near electric field components

InputFile_HFieldX.csv > near magnetic field components

where “X” is the frequency in Hz (e.g., X = 300000000 for a frequency of 300 MHz). So, a FarField, EField and HField file will be generated for each frequency if a frequency sweep simulation has been set.
