Revolution#
This example demonstrates creating a more complex axisymmetric geometry using a revolution operation.
Setup#
mkdir -p TRUST_tutorials/salome/exo2

Creating Edges#
Create straight lines: New Entity → Basic → Line
Line_1: Vertex_1 to Vertex_2
Line_2: Vertex_2 to Vertex_3
Line_3: Vertex_3 to Vertex_4
Line_4: Vertex_6 to Vertex_7
Line_5: Vertex_7 to Vertex_8
Line_6: Vertex_8 to Vertex_9
Line_7: Vertex_9 to Vertex_1
Click “Apply and Close”
Create an arc: New Entity → Basic → Arc
Arc_1: Vertex_4 → Vertex_5 → Vertex_6
Click “Apply and Close”
Creating the Revolution Solid#
Create a wire: New Entity → Build → Wire
Wire_1: Select all lines (Line_1 through Line_7) and Arc_1 (use “Ctrl” for multi-selection)
Click “Apply and Close”
Create a face: New Entity → Build → Face
Face_1: Select Wire_1
Click “Apply and Close”
Create the revolution: New Entity → Generation → Revolution
Name:
Cylinder_1Objects: Face_1
Axis: Click the arrow button and select “OZ” from the Object Browser
Angle:
360°Click “Apply and Close”
Creating Boundary Groups and Mesh#
Create boundary groups: New Entity → Group → Create Group
Follow the same procedure as in the cylinder example
Save your study:
HDF format: File → Save/Save As…
Python format: File → Dump Study…
Create the mesh following the same procedure described in the cylinder section
