As the model has distinct phases of operation, so too can the execution procedures. Users can define a unique execution loop or procedure to account for the different timings, model metrics and outputs required from each stage of the model. In general only 3 are required for the most complex models:
- Atmospheric pressure and pre-stress phase, displacement may be monitored
- DC Bias application, where charge or voltage may be added to monitor list
- Impulse application, where fields in the fluids, along with pressures may be added and plotted.
Stage 1 - Atmospheric Loading:

/* get model timestep symb #get { step } timestep
/* Set-up plotting loops symb nloops = 50 symb nexec = $tAtm / $step symb nexec_loop = $nexec / $nloops

grph plot ydsp i * * j $j2 $j4 plot 4 plot 5 plot 6 imag end
end$ proc
/* Issue PROC $nloops times proc atm $nloops
/* pause - allow to check progress interactively term
Stage 2 - Bias:
c ******************************* c EXECUTE & PLOT - BIAS PHASE c *******************************
/* Set-up plotting loops symb nloops = 50 symb nexec = ( $tRamp + $tBias ) / $step symb nexec_loop = $nexec / $nloops
proc bias save

grph plot ydsp i * * j $j2 $j4 rang 0 -8e-6 plot 4 plot 3 plot 6 imag end
end$ proc
proc bias $nloops
symb #msg 1 ** DRLX OFF **
/* Turn off Dynamic Relaxation for active calculation drlx 0.0
Step 3 - Impulse response:
c ********************************* c EXECUTE & PLOT - ACTIVE PHASE c *********************************
/* set-up plotting times for active part symb nloops = 100 symb nexec = $tSim / $step symb nexec_loop = $nexec / $nloops
grph nvew 4 1 disp 1.
proc active save
exec $nexec_loop
grph plot aprs i * * j $j2 * rang 0 2.5 plot 4 plot 5 plot 6 imag end
end$ proc
proc active $nloops
