$Thermallattice is the command to setup the thermal expansion coefficient of material, which is used with the command $solveheatstrain, $heatstrainsteps.

The command is relative complication, type common format is 

$Thermallattice
type_1  Number_of_input_parameters_N1  $p_{1}$   $p_{2}$   $p_{3}$   $p_{4}$   ....  $p_{N1}$ 
type_2  Number_of_input_parameters_N2  $p_{1}$   $p_{2}$   $p_{3}$   $p_{4}$   ....  $p_{N2}$ 
type_3  Number_of_input_parameters_N3  $p_{1}$   $p_{2}$   $p_{3}$   $p_{4}$   ....  $p_{N3}$ 
 ....
 .... top total layers
type_m  Number_of_input_parameters_Nm  $p_{1}$   $p_{2}$   $p_{3}$   $p_{4}$   ....  $p_{Nm}$

Type:
1: means  latticeXYZ (T) = latticeXYZ(Tref) + latticeXYZ(Tref) * (T -  $p_{1}$  ) *  $p_{2}$  
2: meanx x y z axis have different thermal expansion coefficient. So 
   latticeX (T) = latticeX(Tref) + latticeX(Tref) * (T -  $p_{1}$  ) *  $p_{2}$  
   latticeY (T) = latticeY(Tref) + latticeY(Tref) * (T -  $p_{1}$  ) *  $p_{3}$  
   latticeZ (T) = latticeZ(Tref) + latticeZ(Tref) * (T -  $p_{1}$  ) *  $p_{3}$
