Meshing - General ◆ To reduce overall mesh size, confine small cells to areas where they are needed (e.g., where high gradients are expected). ◆ Controlling cell size distribution ⚫ Edges, Faces and Volumes can be directly meshed ◼ A uniform mesh is generated unless pre-meshing or sizing functions are used. ⚫ Pre-meshing ◼ Edge meshes can be graded (varying interval size on edge) ◼ Graded edge mesh can be used to control distribution of cell size in face mesh. ◼ Controlling distribution of cell size in face mesh also controls distribution of cell size in volume mesh. ⚫ Sizing Functions ◼ New feature to control cell size in faces and volumes directly. Edge Meshing ◆ Edge mesh distribution is controlled through the spacing and grading parameters. ◆ Using the Edge meshing form ⚫ Picking ◼ Temporary graphics ◼ Links, Directions ⚫ Grading/Spacing ⚫ Special characteristics ◼ Apply and Defaults ◼ Invert and Reverse ⚫ Options Picking Edges for Meshing ◆ Picking ⚫ Temporarily meshed edges ◼ When you pick an edge, the edge is temporarily meshed using white nodes ◼ Dis yed edge mesh is based on current grading and spacing parameters ◼ If you modify the scheme or spacing, the temporary mesh will be immedia y updated ◼ When you Apply, the mesh nodes will turn blue ⚫ Sense ◼ Sense is used to show direction of grading ◼ Every picked edge will show its sense direction using an arrow ◼ The sense can be reversed by a shift-middle click on the last edge picked (this is in additi
