## 2.3. Details of the Mesh Import API

This section contains information about the functions that are used to write a customized import executable in the Mesh Import API.

Before trying to use any of the routines listed in this section, it is highly recommended that you read Creating a Custom Mesh Import Executable for CFX-Pre.

This section contains details of:

- Defined Constants

- Initialization Routines

- Termination Routines

- Error Handling Routines

- Node Routines

- Element Routines

- Primitive Region Routines

- Composite Regions Routines

- Explicit Node Pairing

- Fortran Interface

- Unsupported Routines Previously Available in the API

Note: In past releases of ANSYS CFX the API has defined IDs of nodes and elements as integers (int). This release now uses a datatype ID_t to represent these quantities. This type is currently defined as an unsigned integer (unsigned int). This allows a greater number of nodes and elements to be imported than in the past.
