Hello everyone!
I decided to calculate the free-molecular flow around bodies of rotation. I am using the dsmcfoamplus module in OpenFoam 2.4.0-MNF. As an example I use the calculation of the Orion capsule (https://github.com/Eliasfarah0/dsmcF...dule/tree/main). For my example I set the flow velocity to 7000 m/s, the temperature to 196 K and the same gas parameters as in the Orion example. As a result of the calculation, I want to obtain the pressure and temperature distribution over the surface of the streamlined body. BUT! In the example and in the articles, the boundariesDict initially sets the boundary condition DiffuseWall and the temperature at the body wall, although this is something that I do not know initially and want to find. It seems that the zeroGradient boundary condition should be used, but OpenFoam gives an error if I use it. Please help me how to correctly set the boundary condition on the body wall.
The boudariesdict code is below, the model image is https://ibb.co/hHxTBn1.
