The construction of the matrix [K ] and the vector of actions {F } is based on data whose representation may vary. In all cases, we need to characterize a vector {X } of random variables of dimension nva. This is very simple if the variables {X } are direct data present in the code input file, more complicated if they result from the discretization of a random field.
