Non deterministic results in Graphviz (dot) - graphviz

Question

How can I force graphviz to always generate the same layout?
Given a graph:
digraph {
subgraph clusterA {
subgraph clusterB {
"B.001"
"B.002"
"B.003"
"B.004"
}
subgraph clusterC {
"C.001"
"C.002"
"C.003"
}
}
subgraph clusterD {
subgraph clusterE {
"E.001"
}
subgraph clusterF {
"F.001"
"F.002"
"F.003"
}
subgraph clusterG {
"G.001"
"G.002"
}
}
subgraph clusterH {
"H.001"
}
"G.002" -> "F.003"
"F.001" -> "C.003"
"G.002" -> "F.002"
"G.002" -> "D.001"
}
When I pass it to dot it sometimes generates results with layout like this one:
and sometimes like this one:
Obviously the first one looks much better and I would like graphviz to stick to this one.
I tried to pass my graph through fdp and unflatten, but it doesn't change anything.

I tried a lot different render-solutions online and cli. I can't see another output then your second one. But if you prefer the first one, just switch the order of ClusterB and ClusterC.
digraph {
rankdir=TB
subgraph clusterA {
subgraph clusterC {
"C.001"
"C.002"
"C.003"
}
subgraph clusterB {
"B.001"
"B.002"
"B.003"
"B.004"
}
}
subgraph clusterD {
subgraph clusterE {
"E.001"
}
subgraph clusterF {
"F.001"
"F.002"
"F.003"
}
subgraph clusterG {
"G.001"
"G.002"
}
}
subgraph clusterH {
"H.001"
}
"G.002" -> "F.003"
"F.001" -> "C.003"
"G.002" -> "F.002"
"G.002" -> "D.001"
}
