Initial conditions

The syntax is similar to a traditional Prescribed Displacements:

 metafor.getInitialConditionSet().define(gObject, field, ampl)
 metafor.getInitialConditionSet().define(gObject, field, ampl, fctMultiChamps , fieldList)

`gObject`	meshed geometric entity where the displacement is imposed
`field`	variable to be initially fixed. Either a db field Fields at Nodes : displacement, speed, temperature, … or an internal value Fields at Gauss Points : Epl, SigXX, P, …
`ampl`	initial value
`fctMultiChamps`	Functions y=f(t) (spatial dependency of initial conditions)
`fieldList`	list of dependency fields (TX, TY, TZ)
