At a glance

Apply forces and pressures to structures. An agent skill from Cai-aa/CAE-Agent-Hub.

  • Works in 2 steps: Which Load Type? → When to Convert Force to Traction
  • User asks to apply a force
  • SKILL.md covers When to Use This Skill, Key Decisions, Sign Conventions and What to Ask User, plus 7 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Abaqus Load is an agent skill from Cai-aa/CAE-Agent-Hub. Apply forces and pressures to structures. Use when user asks to apply a force, add pressure, put a load on, or mentions gravity, point loads, or distributed forces.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files (for example `UPSTREAM.md` and `metadata.json`).

The licence is MIT.

When your agent uses it

  • User asks to apply a force
  • Mentions gravity
  • Distributed forces

Example prompts

  • “/abaqus-load”

Requirements

  • Pre-approved tools (allowed-tools): Read, Write, Edit, Glob, Grep, Bash(abaqus:*)

Workflow steps

2 steps, taken from the step headings in SKILL.md.

  1. Which Load Type?
  2. When to Convert Force to Traction

What it can do on your machine

Read from SKILL.md and the folder at commit 194ef49. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Write
    • Edit
    • Glob
    • Grep
    • Bash(abaqus:*)

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Abaqus Load loads about 1.2k tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 486 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~44
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Abaqus Load Skill

Apply mechanical and thermal loads to FEA models - forces, pressures, gravity, and heat flux.

When to Use This Skill

Route here when user mentions:

  • "Apply a force", "add pressure", "put a load on"
  • "Gravity", "self-weight", "body force"
  • "Point load", "distributed load", "traction"
  • "Heat flux", "thermal load"
  • "Force in the X/Y/Z direction"

Route elsewhere:

  • Fixed supports, displacements, symmetry → /abaqus-bc
  • Contact forces between parts → /abaqus-interaction
  • Initial temperature fields, pre-stress → /abaqus-field
  • Time-varying load profiles → /abaqus-amplitude

Key Decisions

1. Which Load Type?
User DescribesLoad TypeUnits
Force at a point/vertexConcentratedForceN
Force spread over surfaceSurfaceTractionMPa
Normal pressure on surfacePressureMPa
Force along edgeLineLoadN/mm
Self-weight, accelerationGravitymm/s²
Heat input to surfaceSurfaceHeatFluxmW/mm²
Convective cooling/heatingFilmConditionmW/(mm²·K)
2. When to Convert Force to Traction

If user gives total force but it must be distributed:

Traction (MPa) = Total Force (N) / Surface Area (mm²)

Example: 1000 N on a 50×20mm face = 1000 / 1000 = 1.0 MPa

Sign Conventions

Load TypePositive (+)Negative (-)
PressureCompression (into surface)Tension (away from surface)
Force components (cf1, cf2, cf3)Positive axis directionNegative axis direction
GravityPositive axis accelerationNegative axis (comp2=-9810 for -Y)

What to Ask User

If not specified, clarify:

QuestionWhy It Matters
Force magnitude?Required for all loads
Direction (X, Y, Z)?Needed for directional loads
Point or distributed?Determines ConcentratedForce vs SurfaceTraction
Which surface/vertex?Defines load application region
Constant or time-varying?May need amplitude definition

Direction Specification

Load TypeHow Direction Works
ConcentratedForcecf1, cf2, cf3 = X, Y, Z components
SurfaceTractiondirectionVector=((origin), (endpoint))
PressureAlways normal to surface (no direction needed)
Gravitycomp1, comp2, comp3 = acceleration components
LineLoadcomp1, comp2, comp3 = force/length components

Common Scenarios

Standard Gravity Setup
  • Acceleration: comp2 = -9810 mm/s² (for -Y direction)
  • Requires material density defined - without it, gravity has no effect
Show full SKILL.md (195 more words)Show less
Pressure vs Traction
  • Pressure: Always normal to surface, simpler to define
  • Traction: Arbitrary direction, use when force isn't perpendicular
Thermal Loads
  • Heat flux: Direct heat input (mW/mm²)
  • Film condition: Convection with ambient temperature

Time-Varying Loads

For loads that change over time:

  1. First define amplitude using /abaqus-amplitude
  2. Reference amplitude name when creating load

Modifying Loads Across Steps

ActionMethod
Change magnitudesetValuesInStep()
Turn off loaddeactivate()
Different load in each stepCreate load with step name

Troubleshooting

ProblemLikely CauseSolution
Zero reaction forcesWrong direction or tiny magnitudeCheck direction vector and units
Gravity has no effectMissing densityAdd density to material definition
Load region not foundTypo in set/surface nameVerify name matches exactly
Equilibrium not achievedLoad too largeReduce magnitude or improve convergence
Negative eigenvalueStructure unstableCheck BCs provide adequate support

Validation Checklist

Before running analysis:

  • Load applied to correct region (surface, vertex, edge)
  • Direction matches physical scenario
  • Magnitude in correct units (N, MPa, mW/mm²)
  • Load assigned to correct step (not Initial)
  • Density defined if using gravity
  • Reactions should balance applied loads
