====== Thermomechanical coupled integration scheme ======

===== Description =====

Used if ''MDE_NDYT=1''. The mechanical scheme must be quasi-static (''MDE_NDYN=0''). The thermal scheme is trapezoidal (''MDE_THTY=1'') or generalized midpoint (''MDE_THTY=0'') (see [[doc:user:integration:general:parameters]]).

===== Data set =====

==== Old Metafor Version <= 2422 ====

Any test case running using the staged scheme can be run using the coupled one. The only restrictions are
  * ! no analytic stiffness or divergence 
  * ''MDE_NDYT'' equal to 1. 


==== New Metafor Version > 2422 ====

<code>
tiMech = AlphaGeneralizedTimeIntegration(metafor)
tiTher = MpgThermalTimeIntegration(metafor)
tiTher.setTheta(_theta)
ti = CoupledTmTimeIntegration(metafor)
ti.setMechanicalTimeIntegration(tiMech)
ti.setThermalTimeIntegration(tiTher)
metafor.setTimeIntegration(ti)
</code>

The mechanical time integration scheme is either quasi static or alpha generalized family. The default _theta  parameter value is 1.0 ([0,1]).
