Hi
I'm trying to create a block with 6 vertices. I followed the instruction on page U-142 in the user Guide but I got some strange shape of the block. I guess it is because it assumes that the vertices on the collapsed side have the same y values, which is not the case in my problem. I have attached a sketch of the geometry. There is no problem defining the 8-cornered blocks at the sides but the 6-cornered blocks are not easy to define if they have to have the right x, y, and z direction as the other 8-cornered blocks. I tried the following: 8-cornered blocks hex (7 3 11 15 4 0 8 12) hex (0 1 9 8 4 5 13 12) hex (2 6 14 10 1 5 13 9) hex (7 6 14 15 3 2 10 11) 6-cornered blocks hex (1 0 8 9 1 2 10 9) hex (3 2 10 11 3 0 8 11) This gives the right geometry but when I run the simulation it takes 20 times as much time to get results as when I remove the triangles in the middle and just define a square block! Am I defining something wrong the two last blocks? NB. I need these triangular blocks to define a wall in the middle afterwards. |

Greetings Hale,
If you could provide an example case, it would be easier to experiment this ourselves. Beyond this, my suggestion is to step back a few steps and use the cavity tutorial as an example for gradually creating collapsed edges. For example:
