- Mapdl.mpread(fname='', ext='', lib='', **kwargs)¶
APDL Command: MPREAD
Reads a file containing material properties.
File name and directory path (248 characters maximum, including directory). If you do not specify the LIB option, the default directory is the current working directory. If you specify the LIB option, the default is the following search path: the current working directory, the user’s home directory, MPLIB_DIR (as specified by the /MPLIB,READ,PATH command) and /ansys_dir/matlib (as defined by installation). If you use the default for your directory, you can use all 248 characters for the file name.
Filename extension (eight-character maximum).
Reads material library files previously written with the MPWRITE command. (See the description of the LIB option for the MPWRITE command.) The only allowed value for LIB is LIB.
Material properties written to a file without the LIB option do not support nonlinear properties. Also, properties written to a file without the LIB option are restored in the same material number as originally defined. To avoid errors, use MPREAD with the LIB option only when reading files written using MPWRITE with the LIB option.
If you omit the LIB option for MPREAD, this command supports only linear properties.
Material numbers are hardcoded. If you write a material file without specifying the LIB option, then read that file in using the MPREAD command with the LIB option, the ANSYS program will not write the file to a new material number. Instead, it will write the file to the “old” material number (the number specified on the MPWRITE command that created the file.)
This command is also valid in SOLUTION.
