I recently started using LuaLaTeX (after years of just pdflatex) and I seem to be having trouble with the bm
package. For example, when I try to compile the simple document:
\documentclass[12pt]{article}
\usepackage{bm}
\begin{document}
I really want to be able to use the ``bm'' bold math symbols,
to reproduce something like
\[\frac{\partial \bm{u}}{\partial t}+\left(\bm{u}\cdot\nabla\right)\bm{u}-
\,\textbf{div}\,\bm{\sigma} = \bm{f}.\]
\end{document}
I get lots of !Invalid math code. \bm@command->\mathchar
type errors and the \bm{u}
s are replaced with uppercase gammas (but the \bm{\sigma}
seems to work just fine). I tried adding \usepackage{unicode-math}
both before and after the call to the bm
package, but that seems to mess things up quite a bit. I'm sure I'm just missing something simple here.

Actually, after looking at the bm
package documentation, it seems that it works fine if I use \bm{{u}}
instead of just \bm{u}
. But this seems like a hack - again, the only thing I did was change from pdflatex to lualatex.
