Md Ibrahim Kholil It is determined by the program used for the analysis. If you're working with commercial finite element analysis software, you should be able to export results like volume data to Excel. Before exporting volume data for only the display group, make sure that only the desired items are chosen.

If you're working with a more general-purpose program like MATLAB, you may develop a script to extract the necessary data and export it to Excel. The script would have to access the data in the display group, extract the volume data for the selected items, and save it to an Excel file.

The following is a general summary of the actions you would need to do in MATLAB:

1. Load the display group's data into MATLAB.

2. Only the necessary elements should be chosen from the data.

3. Using the xlswrite function, save the specified data to an Excel file.

Here's an example of how the script may look:

% Load the data from the display group

data = load('display_group_data.mat');

% Select only the required elements

selected_data = data(data.element_id == desired_element_id);

% Write the selected data to an Excel file

xlswrite('volume_data.xlsx', selected_data);

Please keep in mind that the preceding code is only an example and may need to be updated depending on the unique data structure and format.
