How to verify and troubleshoot a turbomachinery model?
This article outlines methods to verify proper model functionality, with a focus on fundamental turbomachinery model checks.
Details
Model checks are a set of verification processes used to ensure the accuracy, quality, and reliability of a simulation model. You will learn:
- Reasons for conducting model checks.
- Common issues and suggestions for units, expressions, materials, thickness, and mesh density.
- Evaluating element quality and orientation.
- Identifying coincident and duplicate nodes.
- Conducting geometry checks.
- Assessing mass properties.
- Verifying thermal couplings.
- Checking radiation enclosures.
- Reviewing model setup and log files.
- Configuring solution settings.
- Resolving ID conflicts.
- Diagnosing thermal results and setup.
- Generating contour plots of boundary conditions.
- Visualizing convective thickness and area factors.
- Illustrating dependencies between boundary conditions, such as temperature or mass flow.
- Checking fluid pressures on walls.
- Verifying mass flow and stream nominal directions.
- Analyzing temperature gradients.
- Analyzing results
- Resolving warnings.
- Troubleshooting the thermal solver.
- Addressing thermal-structural issues.
- Resolving thermal mapping issues.
- Best practices.
