this function is designed to be called in the builder and solver to introduce the selected time integration scheme. It "asks" the matrix needed to the element and performs the operations needed to introduce the seected time integration scheme.
this function calculates at the same time the contribution to the LHS and to the RHS of the system

inlineoverridevirtual |
This function is designed to be called once to perform all the checks needed on the input provided. Checks can be "expensive" as the function is designed to catch user's errors.
