Thank you for all these replies. They give me a high energy for restarting the development of the program.

I just want to give some precisions :

I'm writing the Soft body simulation. But what is, for me, a soft body. A soft body is "clothe" which is defined as a closed volume. This property allows to fill the mesh by volumetric elements (tetrahedrons). Then, the simulation is not made only on the surfaces but on all the volume of the clothe. The simulation made with the pillow would be impossible on a simple surface simulation.

The simulation of the soft parts of the body is, for me, another problem. Some years ago, I resolved this by creating a wire whom the displacement modified some morph parameters. I made this on the chest. This program was sold here, at Renderosity and was called DynaChest. https://www.renderosity.com/mod/bcs/dynachest/66004. I don't know if this program is yet sold at the marketplace now. If you want to test is, don't buy it (if sold), I can send you the program by email. This program works on Poser with Victoria 4. I explain you the principle of this program : A wire is placed on each breast. The rigidity of this wire can be modified. When the animation is played, the wire moves following the movement of the body (and the breasts). All these movements are recorded and each displacement of the wire modifies a morph (chest : right, left, up, down). The final movement is realistic because it corresponds perfectly to the animation. I wanted to make another development for this function (not included in ClothAndHair), sorry!! My goal is to expand this function to all the body. The program would allow to select a vertex, to define the stiffness of the wire and the movement of the wire placed on this vertex will modify 4 morph parameters, for the 4 directions. Tell me if my explanations are clear enough and if you think this program would be useful to you.

For the 64 bits version, I have to install a new computer with my compiler and the library. I don't want to make these tests on my current computer. I will give you the results of these tests. The program will be compiled in 32 and 64 bits.

For the GPU, I really have to find why the Self-Collision don't work correctly. I am sure there is a very simple error in the source. Perhaps, I will ask some help to resolve this issue.

I hope this will reply to your questions. If I forgotten something, please tell me.
