mpamod

Mapdl.mpamod(mat='', deftemp='', **kwargs)

APDL Command: MPAMOD

Modifies temperature-dependent secant coefficients of thermal expansion.

Parameters
  • mat – Material number for which the secant coefficients of thermal expansion (SCTE’s) are to be modified. Defaults to 1.

  • deftemp – Definition temperature at which the existing SCTE-versus- temperature tables were defined. Defaults to zero.

Notes

This command converts temperature-dependent SCTE data (properties ALPX, ALPY, ALPZ) from the definition temperature (DEFTEMP) to the reference temperature defined by MP,REFT or TREF. If both the MP,REFT and TREF commands have been issued, the reference temperature defined by the MP,REFT command will be used.

This command does not apply to the instantaneous coefficients of thermal expansion (properties CTEX, CTEY, CTEZ) or to the thermal strains (properties THSX, THSY, THSZ).

See Linear Material Properties in the Mechanical APDL Material Reference and the Mechanical APDL Theory Reference for more details.

This command is also valid in SOLUTION.
