How can I export the time-varying force acting on a specified object, such as a simulatedrigid barrier in GeoXPM?

Hi @damduchung_huce_66,
The available outputs do not include forces for soil or boundary elements (force outputs for structural elements are only available in the collaborative version). To estimate forces on soil or boundary objects, you’ll need to extract the stress values and multiply them by the relevant areas.
Time can be back-calculated using the timestep. Details about the timestep and simulation time are recorded in the output log, saved in the project directory under _out\Run.out.

@damduchung_huce_66 We don’t have a specific tutorial for this.
In ParaView, you can use “Select Points On”, “Select Points Through”, or apply “Data Filters” to extract particles at the desired locations for plotting.
Alternatively, you can export the data to Excel files and process them using Python or MATLAB.
