  We consider the numerical approximation for a class of radial Dunkl processes
corresponding to arbitrary (reduced) root systems in $\mathbb{R}^{d}$. This
class contains some well-known processes such as Bessel processes, Dyson's
Brownian motions, and Wishart processes. We propose some semi--implicit and
truncated Euler--Maruyama schemes for radial Dunkl processes, and study their
rate of convergence with respect to the $L^{p}$-sup norm.
