# dynareadout

An Ansi C library for parsing binary output files of LS Dyna (d3plot, binout) with bindings for go.

## Examples

### Binout

```go

package main

import (

	"fmt"

	dro "github.com/PucklaJ/dynareadout_go"

	"os"

)

func main() {

	// This library also supports opening multiple binout files at once by globing them

	binFile, err := dro.BinoutOpen("simulation/binout*")

	if err != nil {

		fmt.Fprintln(os.Stderr, "Failed to open binout:", err)

		return

	}

	defer binFile.Close()

	// Print the children of the binout

	children := binFile.GetChildren("/")

	for i, child := range children {

		fmt.Printf("Child %d: %s\n", i, child)

	}

	// Read some data. The library implements read functions for multiple types

	nodeIds, err := binFile.ReadInt32("/nodout/metadata/ids")

	if err != nil {

		fmt.Fprintln(os.Stderr, "Failed to read node ids:", err)

		return

	}

	for i, nid := range nodeIds {

		fmt.Printf("Node ID %d: %d\n", i, nid)

	}

}

```

### D3plot

```go

package main

import (

	"fmt"

	dro "github.com/PucklaJ/dynareadout_go"

	"os"

)

func main() {

	// Just give it the first d3plot file and it opens all of them

	plotFile, err := dro.D3plotOpen("simulation/d3plot")

	if err != nil {

		fmt.Fprintln(os.Stderr, "Failed to open d3plot:", err)

		return

	}

	// Read the title

	title, _ := plotFile.ReadTitle()

	fmt.Println("Title:", title)

	// Read node ids

	nodeIds, _ := plotFile.ReadNodeIDs()

	fmt.Println("Nodes:", len(nodeIds))

	for i, nid := range nodeIds {

		fmt.Printf("Node %d: %d\n", i, nid)

	}

	// Read node coordinates of time step 10

	nodeCoords, _ := plotFile.ReadNodeCoordinates(10)

	for i, c := range nodeCoords {

		fmt.Printf("Node Coords %d: (%.2f, %.2f, %.2f)\n", i, c[0], c[1], c[2])

	}

}

```
