- General parts
- Assemble
- Solid welding (Mesh to Mesh)
- Solid welding (Radial meshing）
- Laser welding
- FE modeling
- Renumber
- Material property
- Local Coordinates
- Export and Run solver
Auto extract of midplane
- Target parts for midplane are selected in the table, then it will extract midplane in automatically.
- Auto select and status are common option in all commands.
- There are status in the table. User can find error in each part in the table.
- User can zoom-up the target part by click in the table.
Auto meshing for Pipe/Rod/Flange
- Mesh according to the provisions specification.
- Ex) Pipe
- Regular mesh （Quad）
- Circumferential direction is divided to 36.
- Zooming mesh in specific area
- Whole : 5mm
- Near weld line : 2mm
- Delete tiny faces
- Ex) Rod
- Regular mesh （Quad）
- Mesh size : 2mm
- Ex) Flange
- Matching of mesh division between pipe and flange opening.
- Fillets are divided to 4.
Auto assembly by rigid elements / solid part
- RBE connection for laser welding.
- Weld bead is changed to solid mesh model, and they are connected by share nodes.
Auto assembly by solid part and radial meshing
- Radial meshing around connection area with weld bead.
- Weld bead is changed to solid mesh model, and they are connected by share nodes.
Package of Pre – Solver – Post
- Jupiter-Pre -> TS-Solver -> Jupiter-Post
Reporting by Jupiter-Post
- Reporting function
- Results are pasted to ppt.
Extension to Acoustic analysis
- Extension to Acoustic analysis
Comparing of modeling time
