SEG-Y format

SEG-Y is a sequential trail format designed for storing fully or partially processed seismic data.

https://en.wikipedia.org/wiki/SEG-Y

To record the selected calculation results in the SEG-Y format, it is necessary to place the Receivers on the model in the preprocessor (Command Panel, Mode - Receivers, Operation - Create).

Select from the drop-down list the geometric entities that will be receivers.

Specify which data fields to save in SEG-Y format.

Installed receiver lines are displayed in the Tree on the left in the Results Settings section.

Viewing data in SEG-Y format is possible in the FidesysViewer postprocessor, and you need to open the file with the .sgy extension.

In FidesysViewer, it is possible to select the required subregions of the model using the Slice / Clip filters (Menu - Filters - Alphabetical Index - Slice).

An example of the resulting SEG-Y file for Vy speed in CAE Fidesys:

Features of writing data to the * .sgy file

All data in the file header, with the exception of the results themselves, are written in integer form.
The time step (recording step) is recorded in microseconds.
The coordinates of the receiver are recorded in meters (If the distance between receivers is less than one meter, then the coordinates of the paths may coincide, and the wave pattern may be incorrect).
Inline number coincides with the id of the node in which it is specified, the Crossline number matches the line number of the receivers.
