5.8.2    Importing fields

Fields Monitor window allows viewing fields saved in files by using  button in Monitor tab of QW-Simulator and Fields->Saved Monitor Fields command from main menu of QW-Simulator.

Import (load) of fields monitor results is available from the following file format:

• QuickWave monitor fields native format: *.fm3

5.8.2.1   Imported fields envelope

FDM Envelope was designed to process Frequency Domain Monitor Files previously saved from the simulation. When the results from *.fm3 file are opened in Saved Monitor Fields window, the Monitor->FDM Envelope menu with its options becomes available.

 - allows the user to set several fields monitor *.fm3 files for further processing. After files selection, in the Log Output tab of Simulator Log window an exemplary log text will appear:

FDM files set list:

X:/test/1.fm3

X:/test/2.fm3

X:/test/3.fm3

 - enables calculation of average value of the fields values included in files from the fields monitor files set list e.g. in files 1.fm3, 2.fm3, 3.fm3 etc.. As a results of calculation new file, containing average values will be created. In general:

avr. value = (value_1 + value_2 + … + value_n)/n

where value_i is taken from subsequent file.

After the calculation process is complete, log message similar to that below is displayed in the in the Log Output tab of Simulator Log window:

FDM file with average values was saved to file:

X:/test/1_average.fm3

It is necessary that all the files taking part in the calculation must have the same dimensions of the data domain! Files saved for the same monitor but for different frequency obey this condition.

 -  enables extraction of envelope maximum value of the fields values included in files from the fields monitor files set list e.g. in files 1.fm3, 2.fm3, 3.fm3 etc.. As a results of calculation new file, containing maximum values will be created. In general:

env. value = max(value_1, value_2, ….value_n)

where in value_i is taken from subsequent file.

After the calculation process is complete, log message similar to that below is displayed in the Log Output tab of Simulator Log window:

FDM file with envelope values was saved to file:

X:/test/1_average_envelope.fm3

It is necessary that all the files taking part in the calculation must have the same dimensions of the data domain! Files saved for the same monitor but for different frequency obey this condition.

 - enables the conversion of all files from the FDM files set list to the fm3 auxiliary format, where information about analysed circuit geometry shape is stored as a link to shape file (*.sh3). As a default, shape information is included at the end of the fm3 file content just after fields values. However in many cases, fields values can take much less space than shape data. If the FDM files set list originates from the same circuit, the user can save a lot of disk space by invoking the Convert FDM files tosh3 link format option, since only one *.sh3 file will be created and the newly created data files will contain only the link to this *.sh3 file not the entire *.sh3 file content.

After the conversion process is complete, log message similar to that below is displayed in the Log Output tab of Simulator Log window:

FDM files in sh3 link format was saved to file:

X:/test/1_sh3link.fm3

FDM files in sh3 link format was saved to file:

X:/test/2_sh3link.fm3

FDM files in sh3 link format was saved to file:

X:/test/3_sh3link.fm3

The name of the *.sh3 file will be extracted from the name of the first file on the FDM files set list, e.g. 1.fm3 file results in 1_average_envelope.sh3.
