The source file: An LS-DYNA simulation result file containing stresses, strains, and history variables such as a dynain file or simulation results from third party tools (Moldflow, Moldex3D, Theseus-FE, etc.).

The target file: Generally, an LS-DYNA mesh that will be used for a subsequent analysis. A target mesh is usually optional, and is only required if you want to map to a different mesh. If you only want to manipulate the data on the source mesh without mapping, you can omit the necessity for the target mesh parameter using the InitializeOnSource command.

The mapping.in file: Contains the main mapping commands. This file's name is used by the user interface (UI) by default, if no other file name is provided. The mapping.in file contains information about the source file, including the file names and locations that provide data to be transferred to the target file.

The *.mapout file: A generated file that contains information about the mapping process: required time, data referring to the meshes such as number of nodes, number of elements, amount of created integration points, files being used for the mapping process, and so on. The *.mapout file is renamed depending on if the data transfer was successful.

If the prorgam crashes, the *.mapout file may not get renamed. If that occurs, reach out to your sales representative or the team at envyo@ansys.com with the following information:

The result file: A generated file that contains the data of the source file on the mesh of the target file.
