SetdNTdt

This subroutine set dNTdt by using the space-time nodal values.

• This subroutine set dNTdt by using space-time nodal values
• It is important to note that dNTdXt should be allocated before calling
• This subroutine uses following formula

$$\frac{\partial N^{I\ }T_{a}}{\partial t} =N^{I}\frac{\partial T_{a}} {\partial \theta } J^{-1}_{t}-\frac{\partial N^{I}T_{a}}{\partial x_{k}} \hat{v}_{k}$$

MODULE PURE SUBROUTINE setdNTdt(obj, val)
  CLASS(STElemshapeData_), INTENT(INOUT) :: obj
  REAL(DFP), INTENT(IN) :: val(:, :, :)
  !! Space-time nodal values
END SUBROUTINE setdNTdt
