piecewise polynomial material properties
Posted in the ANSYS Forum
#1 Feb 10, 2012
I would like to describe the heat capacity of copper using a piecewise polynomial function.
I have 4 ranges of temperatures and then 4 different polynomial functions.
I use four times MPTGEN and MP commands to inform about the 4 ranges of temperature and the 5 coefficients of the polynoms for these 4 ranges.
The problem is that ansys re-compute the heat capacity for the previous range of temperature each time I use a new range of temperature...
How can I do to keep in memory the first polynom, the second, etc...?
cuivre = 3 !(OFHC)
MPTGEN,,(Tfinia - Tinia)/deltaT , Tinia, deltaT
MP, C, cuivre, C0a, C1a, C2a, C3a, C4a
MPTGEN, 21,(Tfinib - Tinib)/deltaT , Tinib, deltaT
MP, C, cuivre, C0b, C1b, C2b, C3b, C4b
