Parallel computation

There was a problem with the parallel computation of the 3 nested loops: solved.

In the run condition: -in instead of < corrected the problem.

Comments on the main input file.

Tolerances setup

Need to compute efficiently the drag. It has been used a check condition on the fxTOT value. If the variation of fxTOT is less than a tolerance, tol, the program has reached the convergence.

Separation of the 3 nested loop and the main case properties into: in.plate and in.case.

Nested loops setup and check

Need to compute the aerodynamic coefficients for different Kn, AOA and Ma. It has been implemented a 3 nested loop for the computation of these coefficients.

We got a problem with the tolerances computation between 2 runs.

We solved the problem using a variable definition for the computation of the forces.

The system solution is made with a in.case check of the average aerodynamic forces tolerances.

Lift implementation

The new version has in it the implementation of the lift computation.

Need to pass from the 2D geometry to the 3D geometry.

Temperature setup

Translational, vibrational and rotational temperature setup and checking. Once this check is passed we can switch to the final 3 nested loop simulation.
