User Defined Tabulated Potential
« on: May 4, 2016, 05:47 »
Hi,

What is the starting radius of the user defined tabulated potential? Is it 0 by definition?

Regards,

I don't understand what the context is. Could you give more details?

It always starts at zero distances, see the attached test script.
Now, that you mention it, that would actually be another possibility to implmenent the ZBL-potential.

Hi Julian and Jess,

Thanks for your replies. I ran the attached script and got the results as well. However, I am getting some error while running my script, which I cannot debug. I would be grateful if you could shine some light on it. (I have the tabulated potentials as 60000 points for each pair, 6 in total, and delta_r=0.0001 Angstrom)

Regards,

I can't tell what the problem is without the potential files.
