Question on severity of a runtime warning

[hamsamilton]

Hi,

When running dynamics analyses I frequently receive the following warning

/Users/samhamilton/miniconda3/envs/pwspyenv/lib/python3.11/site-packages/pwspy/analysis/dynamics.py:140: RuntimeWarning: invalid value encountered in log
val = np.log(ac) / (4 * k ** 2) # See the theory section of the paper for an explanation of the 4k^2. The slope of log(ac) should be equivalent to 1/t_c in the paper.

Does this invalidate the results? What are solutions to this issue?
