Thermomechanical coupled integration scheme

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 Global Parameters [REMOVED]).

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.

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

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