Particles forces

[Mohammad Wasfi]

Hi, 

I am trying to obtain the forces the particles experience in my simulation as a CSV file. I am using the GPU module. I have looked and found that I can possibly use the WriteCsvParticles function that is capable of doing that. However, it seems that this is a protected function and can not be accessed. Is there another way that I can obtain the forces on all the particles in the system? 

Thank you so much,

Hi Mohammad,

You should in your script set the output flag such that this information is outputted. The flag is FORCE_COMPONENTS, so the command should look like...

gpu_sys.SetParticleOutputFlags(ABSV | FORCE_COMPONENTS);

Now that you mentioned it, I found no demos is actually using this flag. Maybe it should be changed... Note this flag would give you the total contact force each particle experiences. But if it's the contact force of each contact pair that you are looking for, you'd have to do something different.

Thank you,

Ruochun
