1. Introductionole西班牙语
This RBF-Morph tutorial is termed "Adjust the driver position" and has the principal objective to show the ur how loading previous solutions to customize a combined solution.
This tutorial demonstrates how to do the following:
∙load the RBF-Morph solution gained through a previous analysis;
∙fast lect model surfaces through the pick feature for morphing preview;
∙check the solution;
∙generate and save a morphing quence animation;
∙t up, preview, and check a multi-morph solution.

2. Prerequisites
Requirements for working this tutorial:
1. you are working in the directory where the tutorial problem resides;
2. you have just started the Fluent-GUI application;
3. you have done and adequately understood the previous tutorial.
3. Problem description
This tutorial shows how to adjust the position of a motorbike driver. Figure 1 and Figure 2, through a visualization colored by ID, illustrate the surfaces constituting the model courtesy of the Mechanical Engineering Department of the University of Rome "Tor Vergata [R 1]. In particular, Figure 1 shows the surfaces of the simulation volume, whereas Figure 2 reports the model of the motorbike and biker.

Two modifiers have been previously calculated and the corresponding files are prent in the working directory. The first one changes the driver head angle, whereas the cond one modifies the driver hunching angle. For the first ca the modifier solution t-up will be load whilst, for the cond, the solution itlf will be read.
The solutions will be finally combined to show how it is possible to adjust the driver position in a very straightforward fashion with the driver head in the proper position for looking at the road.
4. Loading and checking existing solutions
The afore-cited solutions, respectively concerning the rotation of the head and body of the driver, will be described in the following paragraphs.
1.1 Driver head rotation (first solution)
1.1.1 Preparation
After starting Fluent from the directory containing the tutorial files:
∙read the test ca tut_02_;
∙open the RBF Morph GUI via the menu Define -> RBF-Morph;
∙load the library by clicking on Enable RBF Model.
Once the library is completely loaded, the panel illustrated in Figure 3 should appear.

Verify that, apart from the . file, the following files are prent in the working directory: ∙rotate-head.rbf;
∙rotate-head.sol;
∙rotate-driver.rbf;
∙rotate-driver.sol.
1.1.2 Overview of the solution t-upquartz
The first solution of interest, named rotate-head, rotates the driver head. This solution has been previously generated and it is prent in the working folder. In this ca, the strategy is to load the solution t-up file. In this view, lect Config in the Main Sidebar panel, press the Select button, choo the rotate-head.rbf file in the general file dialog (e Figure 4), and finally press the Read button.
