**Definition**: `syscVolumeMesh.h` (line 42)

Provide a volume mesh access struct.

To create and/or initialize [SyscVolumeMesh](structSyscVolumeMesh.md#structSyscVolumeMesh), it is highly recommended to use one of the functions with names starting with `syscGetVolumeMesh`. These functions will initialize all members to the correct values and will help to avoid back-compatibility issues in the future. For example:

```
SyscVolumeMesh mesh = syscGetFaceBasedVolumeMesh(
    nodeCoords, elemNodeCounts, elemNodeIds);

```
