Advective heat transport using coupling of Heat_Transport and Deformation_Flow

[ThieJan]

The advective heat transport seem not to work for this coupling.

So far I initialized the coupling pointer of heat transport process to flow process in case the monolithic HM (Deformation_Flow) is used.

Not working yet. See #162

@ThieJan Sorry, I did not have time before to check your correction. The correction is good, which gives the advection effect as shown in the following Fig. The T-H-M gives an inaccurate velocity with only one coupling iteration. I think that the benchmark by P. Vogel ' ignores the strain coupling to M.

With this correction and increasing the coupling iterations in T-H-M, the velocity profile in T-H-M is non constant as expected. With more coupling iterations and small time step size, the velocity by T-H-M is more close to that by T-HM. Here is the changed num file of T-H-M, in which you can increase the coupling iteration to get more accurate HM variables.:
