Claude-skill-registry abaqus-odb

Read analysis results. Use when user asks about maximum stress, extracting displacements, reaction forces, or exporting results. Post-processes ODB files.

Abaqus ODB Skill

This skill reads and extracts analysis results from Abaqus ODB files.

When to Use This Skill

Route here when user mentions:

"What is the maximum stress?", "extract displacement"
"Get reaction forces", "post-process the ODB"
"Export results to CSV", "what are the eigenfrequencies?"

Route elsewhere:

Running the analysis →
```
/abaqus-job
```
Configuring what output to save →
```
/abaqus-output
```
Exporting geometry (STL, STEP) →
```
/abaqus-export
```

Key Decisions

1. What Result is Needed?

Need	Field	Notes
Displacement	`U`	Use `.magnitude` for total
Stress	`S`	Use `.mises` for von Mises
Reaction force	`RF`	Sum components for total
Strain	`E`	Similar structure to stress
Temperature	`NT`	Thermal analysis results
Eigenfrequency	Frame description	Parse from frame metadata

2. Which Step/Frame?

Scenario	Frame Selection
Final results	`step.frames[-1]`
All time history	Loop all frames
Specific time	Find by `frameValue`
Modal analysis	Each frame = mode

3. Location: Global Max or Specific?

Need	Approach
Overall maximum	Loop all values, find max
Specific node	Filter by `nodeLabel`
Subset/region	Use `getSubset(region=...)`

4. Export Format?

Format	Use Case
Print to console	Quick check
CSV file	Spreadsheet analysis
Text report	Documentation

What to Ask User

If unclear, ask:

What result? Stress, displacement, reaction force, frequency?
Which step/frame? Final, specific time, or all?
Location? Maximum anywhere, or specific node/region?
Output format? Print, CSV, or report?

Workflow

Open ODB - Use
```
readOnly=True
```
for extraction
Navigate to step/frame - List steps with
```
odb.steps.keys()
```
Get field output - Access via
```
frame.fieldOutputs['U']
```
Extract values - Loop
```
field.values
```
, use
```
.magnitude
```
,
```
.mises
```
Close ODB - Always close when done

Common Tasks

Task	Approach
Max displacement	Loop U values, find max magnitude
Max von Mises stress	Loop S values, find max mises
Total reaction force	Sum RF components across all nodes
Displacement at node	Filter by nodeLabel
Results in region	Use getSubset with node/element set
Eigenfrequencies	Parse frame.description in frequency step
Time history	Use historyRegions and historyOutputs
Export to CSV	Write values with csv module

Troubleshooting

Error	Cause	Solution
"ODB locked"	Another process has it	Delete `.lck` file
"Key not found"	Wrong variable name	List available keys first
"No values"	Output not requested	Check FieldOutputRequest in model
"AttributeError: mises"	Element has no mises	Check element formulation
