There are two file formats to choose from in the tree, full and compact, and these are further defined by the type of application. Some applications might have been delivered with an MPH-file that contains no stored meshes or solutions. Such compact files are indicated by the icon . Full models are indicated by the icon . See Downloading MPH-Files With Solutions.

It is possible to open and postprocess models that include functionality that you have blocked or that your license does not include. Nodes with functionality that requires a license for a product that is blocked or not available get a License Error subnode (), where you find information about the missing but required product license. Unless you disable or remove such nodes, it is not possible to re-solve such models.

You can enable the Open PDF Document for a user-library model or application by placing a PDF-file with the same name as the MPH-file in the same folder.
