Changing Parameter Defaults

The default parameters that appear in the LineCalc window for editing are set in a file called lcuiinit in the directory $HPEESOF_DIR/linecalc/lib (where $HPEESOF_DIR represents the complete path for your installation). You can make a local copy of this file and change the default parameters so that less editing is required whenever you use LineCalc.
To modify the lcuiinit file:
  1. Copy the file lcuiinit to a directory of your choosing. Using any text editor, make the desired changes. Save the file.
  2. Now you need to tell the program where to look for your customized file. Make a local copy of the LineCalc configuration file linecalc.cfg found in $HPEESOF_DIR/config. Copy this file to $HOME/hpeesof/config.
  3. Using any text editor, locate the variable LCALCUI_INIT_FILE and modify the path to point to the location of your modified lcuiinit file.
    Note
    On the PC, $HOME represents the path you specified as the Home Folder during installation ( C:\users\default by default); $ HPEESOF_DIR represents the path you specified as your Program Folder during installation ( C:\AdvDesSys ).
    The component definition format is:
    ELEMENT <element_name> <element_id> <# of ports> <units> <physical> [<physical_fixed> <physical>] <subst> <tand> <sigma> <temp> <electrical> [<electrical_fixed><electrical>]<result>
    For example:
    ELEMENT COAX COAX_DEFAULT 4 UNITS PHYSICAL PHYSICAL_FIXED PHYSICAL SUBST ELECTRICAL RESULT UNITS UNITS_DEFAULT
    FREQ_VAL=10.00 FREQ=GHz LENGTH=mil RES=ohm ANGLE=deg
    PHYSICAL DI=37.00
    PHYSICAL_FIXED DO=90.00
    PHYSICAL L=650.00
    SUBST COAXSUB=COAXSUB_DEFAULT ER=2.10 TAND=0.0003 RHO=1.0
    ELECTRICAL Z0=35.00 E=90.00
    RESULT A_DB=0.01
