How do I check and control mesh interface intersections?

      Participant

      The user can perform a check on the areas of interface zone types, and grid interface intersections, and automatically generated wall zones by the TUI command: define/mesh-interfaces/list The behavior of the grid interface algorithm is controlled by rpvars as follows: area_tol = RP_Get_Real (“nonconformal/smallest-area-tolerance-factor”); normal_tol = RP_Get_Real (“nonconformal/normal-tolerance-factor”); (nonconformal/smallest-polygon-size 1e-10) is the var to control the dropping of slivers. Note: An intersection is ignored if: 1.Intersection area magnitude is less than “area_tol” times minimum of the two parent face area magnitudes 2.Normal distance is greater than “normal_tol” times the minimum edge length of the parent faces 3.Dot product of the parent face normal is greater than COSINE_TOL which corresponds to 45 deg
