We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

How do I check and control mesh interface intersections?

  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
