Limitations of Automatic Runner Solid Mesh Generation

In the current release, there are some limitations of runner solid mesh generation. The program may fail to generate solid mesh in some situations. When errors occur, the dialog below appears.



We list several cases below and provide a way to walk-around for each case.



A runner end is partially connected with a cavity

The submarine gate is a typical sample of this situation, as following picture. The runner end region is not wholly connected with the cavity.



If this problem occurs, the program may fail to make connection between runners and cavity solid meshes, and thus cannot finish the solid mesh generation. The program can detect the situation automatically and ask you to change the gate location to avoid the problem, as following dialog:




We recommend users to move the gate location from the part boundary to central a little bit.



The runner layout is not changed, except for the gate location; the modified runner line segments are as below. The program can generate the solid mesh successfully afterwards.



A runner is too short to create solid mesh

A main runner is connected with two forks as below figure. When the distance between two fork vertexes is not long enough, the solid mesh of the runner will not create successfully.


It is recommended to increase the length by minimum 1.5 times of main runner diameter as the following picture.





The size of edge gate height is over the radius of runner

If edge gate and runner are perpendicular to one another, the height of edge gate cannot be over the radius of runner. If the size of edge gate is too big, the solid mesh of the runner will not create successfully.


It is recommended to decrease the size of edge gate. Or enlarge the diameter of runner. Please refer to the picture on the left side.
