New option for meshing 3d runner with 3d part

[Anonymous]

There are two possibilities to create a 3d tetra mesh with a 3d runner:

First option:

1. Import part and runner as one cad model
2. Meshing both as one model with tetras
3. After meshing you can define the runner as 3d runner

Disadvantage of this option:

1. You have non planar surfaces in the interface between runner and part
2. It could happen, that the mesher produced a coarser mesh inside the interface region

Second Option:

1. Import part and runner as a separate cad model
2. Define the cad runner as 3d runner
3. Meshing both as separate model with tetras using the option “Precise match”
4. After meshing you have to control, that all nodes in the interface are matching
5. If this is ok, you can merge the interface nodes with a global merge with a low distance e.g. 0,001 mm.

Disadvantage of this option:

1. You must shut off the option “ Use surface mesh optimization”
2. It is a time consuming method

To improve this meshing process I would like to have:

1. An option where I can define the interface surface or elements as a “gate surface”
2. The 3d mesher should now automatically mesh both, runner and part, in 3d and connect them during the meshing
3. The runner and part surface in the interface should be kept as a planar surface

I would also like this for meshes I imported into Synergy without underlying CAD geometry.

This has been accepted. Thanks for the idea.
