Part 1: Create pressure vessel geometryStep 1: ![image.png](media/0EM4O000003e938)
Create a Simcenter Part
•Launch a new session of Simcenter
•File > New
•In the window that appears, select Model from the list of Templates
•Set the Name to Pressure_Vessel.prt
•Choose a suitable directory where the model will be saved
•Click OK
Step 2: Create the Vessel Geometry
•Select Extrude
•Click on the XY plane to start the creation of a sketch
•Draw the depicted shape below using the sketch tools
•Ensure that the indicated line is aligned with the x-axis
Step 3: Create the Vessel Geometry
•Click Finish

to exit the sketch
•Set the Start Extrude limit to 0mm and the End to 0mm
•Click OK
Step 4: Create the SIM and FEM
•File > Pre/Post
Click New FEM and Simulation button

(typically in the top left corner)
•The menu shown to the right should appear
•Ensure that the Create Idealized Part checkbox is checked
•Set the Analysis Type to Axisymmetric Structural
•Set 2D Solid Option to XY Plane, X Axis
•Click OK
Step 5: Set the Solution Parameters for the Analysis
•The menu that appears allows various solution parameters to be set. Check that:
•Solver is Simcenter Nastran
•Analysis Type is Axisymmetric Structural
•Solution Type is SOL 101 Linear Statics
•The default settings will suffice for the other setup options. If necessary, it is possible to modify these settings at a later stage in the model setup process
•Click OK
Step 6: Inspect the Simulation Navigator
•Expand all items in the Simulation Navigator
•Observe the positions of the SIM (.sim), FEM (.fem), and the Part (.prt) in the Navigator
•Ensure that the Simulation File View at the bottom of the Simulation Navigator is expanded as this will make it easier to navigate between the different simulation files
•Double click the Pressure_Vessel_fem1_i part in the Simulation File View pane using the left mouse button. An Idealised Part Warning message should appear
•Click OK
Step 7: Promote the Bodies to the Idealised Part
•Click on the Promote button
•Select the body in the display port
•Click OK
Step 8: Split the Pressure Vessel Section to facilitate Mapped Meshing
•Select the Split Body

tool in the Geometry Preparation group of the Home tab tool ribbon
•Select the pressure vessel section and click the middle mouse button
•Set the Tool Option to New Plane
•Select the point indicated in the image and ensure that the inferred normal for the plane is in the x-direction
•Click Apply
Step 9: Split the Pressure Vessel Section to Facilitate Mapped Meshing
•Repeat the process until the pressure vessel section is split as shown below
