# Certain vanishing of local cohomology supported on some exceptional divisor

Consider $V:= \mathbb{C}^n$ such that $n \ge 3$ and take $p \in V$. Let $\nu \colon \tilde{V} \rightarrow V$ be a composite of blow-ups along smooth centres such that $\nu$ is an isomorphism outside $p$ and $F:= \nu^{-1}(p)$ is a SNC divisor. Let $F' \subset F$ be a divisor which is an union of several components of $F$. We can see that the vanishing of the local cohomology group supported on $F$

$H^2_F(\tilde{V}, \mathcal{O}_{\tilde{V}})=0$

by the local duality and the Grauert-Riemenschneider vanishing theorem.

Question Do we also have $H^2_{F'}(\tilde{V}, \mathcal{O}_{\tilde{V}})=0$ for the above $F'$?
