CAESAR II Modeling Example 1 as per ASME B31.3

CAESAR II Modeling Example as per ASME B31.3 

In this blog post, we walk through a step-by-step modeling example in CAESAR II following the ASME B31.3 piping code. The video demonstrates how to create the model completely — including geometry, properties, loads, and supports — but stops before analysis.

📌 What This Video Demonstrates

This video is part of a playlist guiding users through real pipe modeling in CAESAR II. In this particular lesson, the focus is on how to complete the model setup for a piping system per the ASME B31.3 process piping code. This includes creating the geometry, defining components, assigning materials, adding loads & supports, but it does not include running the analysis.

🧱 1) Starting a New CAESAR II Project

• Select file → New
• Enter job name and description
• Choose the correct unit system for the project
• Select design code: ASME B31.3

📐 2) Defining Geometry

The video shows how to build the piping geometry in CAESAR II using:

• Nodes: Points in space that mark the ends of pipe segments
• Elements: Pipe segments connecting nodes
• Bends.

The goal here is to replicate a real piping layout inside the software so that the model represents the actual field arrangement.

📊 3) Adding Pipe Properties

• Select pipe size and thickness
• Choose schedule number
• Assign internal medium (for weight & pressure effects)

🧪 4) Assigning Material and Temperature

• Select the material type (e.g., carbon steel)
• Input operating and ambient temperatures

🛠 5) Supports and Boundary Conditions

Supports are critical for piping modeling. In this step, the video shows:

• Where to place guides, anchors, and other restraints
• How to assign support stiffness
• Review of support symbols and what they represent

🔎 What You Don’t See in This Video

This tutorial does not proceed to:

• Running the solver and output generation
• Stress, flexibility, and code compliance checks
• Detailed result interpretation

These steps are part of later videos in the playlist if you want to continue the learning sequence.

🧠 Why This Model-Only Lesson Matters

Proper modeling is the foundation of any accurate piping stress analysis. Without correct geometry, supports, materials, and loads, results — no matter how perfect — will be meaningless.

• Accurate modeling = reliable analysis later
• Supports determine real load paths
• Material & temperature inputs affect stress results
