How to Acquire Results from a Simulation Object in Lumerical

Acquiring Results from a Simulation Object in Lumerical

Lumerical – getresults – Script Command for Result Acquisition

Need assistance in acquiring results from a simulation object in Ansys Lumerical?  Thankfully, the process is relatively easy and straight-forward.

Please note, after running the script command, results will be returned as datasets.

Syntax Description
?getresult(“monitor_name”); Returns the names of all the results for the monitor. All the dataset and scalar matrix results will be returned in this case.
R = getresult(“monitor_name”,”T”); Returns the result T from the monitor. T is a dataset.

 

Lumerical getresults Practical Example

This example shows how to get the electric field dataset from a monitor. We then apply a number of operations to the dataset, such as finding the maximum |E|^2 value, viewing the dataset with the visualizer, and creating a plot of Ex at the first frequency point.

Note that E is a dataset, rather than a simple matrix based variable. Data within the dataset can be accessed with the ‘.’ operator, as shown below.

# get Electric field dataset
E=getresult("monitor","E");
# output dataset value to prompt
?E;
# check size of position vectors and data matrices
?size(E.f);
?size(E.Ex);
# find maximum |E|^2 value 
?max(E.E2);
# view dataset with visualizer
visualize(E);
# select first frequency point of Ex data, then create plot
Ex = pinch(E.Ex,4,1); 
image(E.x*1e6,E.y*1e6,Ex,"x (um)","y (um)","Ex");
 E vs x, y, z, lambda/f
 result: 
 5 1 
 result: 
 343 255 1 5 
 result: 
 3.223651
