Field variables read from a file need to consecutive

[david-montiel-t]

For example, in an application where there are 5 field variables (n0,n1,n2,n3 and n4), the code will work if variables n0, n1 and n2 are marked to be read:

set Load initial conditions = true,true,true,false,false

Bur the code will get stuck if variables n0, n1 and n4 are marked, e.g.,

set Load initial conditions = true,true,false,false,true
