Notes about the MPH file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The MPH file type is primarily associated with 'COMSOL Multiphysics' by COMSOL, Inc.. COMSOL Multiphysics is a modeling package for the simulation of any physical process you can describe with partial differential equations. This is an FEA software binary file.
