- file_nameEuler angle data file name
C++ Type:FileName
Controllable:No
Description:Euler angle data file name
EulerAngleFileReader
buildconstruction:Undocumented Class
The EulerAngleFileReader has not been documented. The content listed below should be used as a starting point for documenting the class, which includes the typical automatic documentation associated with a MooseObject; however, what is contained is ultimately determined by what is necessary to make the documentation clear for users.
Read Euler angle data from a file and provide it to other objects.
