Keep in mind that if you are not interested in fully capturing a region then you can ignore the errors within that region. An Error tolerance bar is available to help hide FAVOR problems in regions that are not of interest. The value is a ratio * Here is an example of a missed hole. By right-clicking on the cube and slicing along a direction you can get a better view of the problem. As can be seen here there are multiple surfaces crossing along a mesh plane that are not being captured. Some features may not be important to capture and if you following the meshing guidelines you will not have to use to this option. This option also works with Renderspace. Renderspace is another FAVOR option that allows the user to define a rectangular space with a cell size in order to get an idea of what size is necessary before actually meshing. * Cartesian mesh can be used for flow domain, conforming mesh blocks, and hexahedron. The hexadedron mesh uses the cartesian mesh and then conforms to solid but moving the nodes to solid and also converging it necessary. Hexahedron mesh can be used with conforming mesh blocks for FSI and TSE model. * * This is the same case, but now the conforming mesh is only built around solid component 1: the
