| class(equation), | intent(inout), | target | :: | this | The routine is called on this equation. |
|
| integer(kind=ip), | intent(in) | :: | source | The first source for the update. Can be either -1 (RHS), 0 (main) or between 1 and ntmp (temporary). |
||
| integer(kind=ip), | intent(in) | :: | dest | The destination for the update. Can be either -1 (RHS), 0 (main) or between 1 and ntmp (temporary). |
||
| integer(kind=ip), | intent(in), | optional | :: | source2 | The second source for the update. Can be either -1 (RHS), 0 (main) or between 1 and ntmp (temporary). |
|
| real(kind=wp), | intent(in), | optional | :: | scalar | The scalar multiplying the first source. |
|
| real(kind=wp), | intent(in), | optional | :: | scalar2 | The scalar multiplying the second source. |
The routine that updates the variables defined in an equation. This is used to make the time integrator agnostic to how storage for the variables in the system of equations are set up.
After completion: this%var(dest) = scalar*this%var(source)+scalar2*this%var(source2)
