PARAM, THMLSTN

Bulk Data Entry Select the thermal strain formula.

Parameter	Values	Description
`THMLSTN`	<0, 1>	Selects the thermal strain formula, applicable to Nonlinear Static Analysis only. 0 (Default) $ε_{T} = A (T_{F i n a l}) (T_{F i n a l} - T_{I n i t i a l})$ 1 $ε_{T} = A (T_{F i n a l}) (T_{F i n a l} - T_{R e f}) - A (T_{I n i t i a l}) (T_{I n i t i a l} - T_{r e f})$ Where, $ε_{T}$ Thermal strain. $A (T_{F i n a l})$ and $A (T_{F i n a l})$ Thermal expansion coefficients corresponding to $T_{F i n a l}$ and $T_{I n i t i a l}$ . $T_{I n i t i a l}$ , $T_{R e f}$ and $T_{F i n a l}$ Initial, referent and current/final temperature, respectively.
