API reference

The guides cover the common paths; the complete, generated API for every public item lives here:

Rust

Add the crate and pick the features you need:

[dependencies]
dynars = "1.0"
# dynars = { version = "1.0", features = ["signal", "ffi"] }
Feature Enables
(default) parsing, navigation, validation, d3plot / binout readers
signal result-history signal processing (SAE J211 CFC, Butterworth, integrate/differentiate) and injury criteria
ffi C ABI (and, through it, Fortran) bindings for the parse + validate path
typed-keywords a generated typed struct per keyword (~3170; opt-in)

Python

pip install dynars

The published wheels bundle the signal feature, so filtering and injury criteria are available out of the box. import dynars exposes the core at the top level — parse_deck, Workspace, Rule, D3plot, Binout — with post-processing grouped into submodules: signal processing under dynars.signal (cfc, butterworth, integrate, …), occupant injury criteria under dynars.injury (hic36, resultant, clip, …), and the keyword-name constants under dynars.kw.

Keywords dynars doesn't ship

The built-in library covers thousands of LS-DYNA keywords. For a vendor, newer, or otherwise unlisted keyword, describe its card layout once and get the same typed, columnar access:

deck.register_schema(
    "MY_KEYWORD",
    cards=[[("id", "int", 8, 1), ("value", "float", 16, 1)]],
)
rows = deck.table("MY_KEYWORD")   # now columnar, like any built-in

use dynars::Keyword;

#[derive(Keyword)]
#[keyword("MY_KEYWORD")]
struct MyKeyword {
    id: i64,
    value: f64,
}
