Pfem Melting Application
📝 Description A new application called PfemMeltingApplication is added. This application aims at modelling polymers which can melt by the action of heating. It contains several solvers: the typical fluid solver with remeshing, one fluid solver without remeshing, and a couple of hypoelastic solid solvers. The application can also simulate the effect of a laser, coded as a process. Most of the work (design, coding, testing) has been done by @juliobarna . I (@maceligueta) have just collaborated in proposing ideas and cleaning the code just a bit at the end. Modifications of other applications have been reduced to the minimum, however, maybe @rubenzorrilla should review the changes proposed in the FluidDynamics app, which do not change the behavior of the code.
Test examples are extremely large. Besides they include the auxiliary files generated by GiD which musn't be pushed to the repo.
I removed them all, as examples can be generated really fast with the GidInterface now.
