| description | Create mold/tool geometry for composite curing simulation. Invoke when user needs to set up mold part, tool surfaces, or mold-composite contact geometry. |
This skill creates the mold (tool) part for composite curing simulation. The mold is a
separate part in the Abaqus assembly that contacts the composite outer surface during
curing and is removed in the springback step via *Model Change.
The tool is defined as a separate *Part block with its own nodes, elements, and sets.
It is independent from the composite (P8) part and has its own node and element numbering
starting from 1.
*Part, name=tool
*Node
1, <x>, <y>, <z>
2, <x>, <y>, <z>
...
*Element, type=C3D8R
1, <n1>, <n2>, <n3>, <n4>, <n5>, <n6>, <n7>, <n8>
2, <n1>, <n2>, <n3>, <n4>, <n5>, <n6>, <n7>, <n8>
...
*End Part
toolImportant: Both the tool part and the composite (P8) part start their node and element
numbering from 1. When parsing the INP file, you must parse nodes and elements per-part,
not globally. The assembly-level instance prefix (e.g., tool-1. or P8-1.) distinguishes
them in the assembly context.
The tool material is defined with elastic properties and thermal expansion. It is a linear elastic isotropic material representing the mold (typically steel or aluminum).
*Material, name=TOOL
*Elastic
69000., 0.33
*Expansion
2.52e-05,
| Property | Value | Description |
|---|---|---|
| Young's modulus (E) | 69000. | Elastic modulus in model units (MPa) |
| Poisson's ratio (nu) | 0.33 | Isotropic Poisson's ratio |
| Thermal expansion | 2.52e-05 | Coefficient of thermal expansion (1/C) |
The thermal expansion coefficient allows the mold to expand and contract with temperature changes during the curing cycle, which affects the contact pressure and friction behavior.
The tool elements are assigned the TOOL material via a *Solid Section card:
*Solid Section, elset=_PickedSet2, material=TOOL
,
_PickedSet2 (element set containing all tool elements)TOOL (references the *Material, name=TOOL card)The mold is an L-shaped bracket that matches the composite part shape but extends beyond the composite boundaries to ensure full contact coverage.
| Property | Composite (P8) | Tool (Mold) | Description |
|---|---|---|---|
| In-plane length | 100 mm | 120 mm | Mold extends 10 mm beyond each end |
| Through-thickness | 1 mm | (mold body) | Mold is a solid body, not a shell |
| Shape | L-shaped | L-shaped | Matching bracket geometry |
The mold extends beyond the composite (e.g., 120 mm vs 100 mm) so that the contact surface fully covers the composite outer surface even after thermal expansion and deformation during curing.

| Tool (Mold) | 120 mm

+---+---------------+

| Composite | 100 mm (inside mold)
| (P8) |
+---------------+
The composite sits inside or against the mold. The mold's inner surface contacts the composite's outer surface (S1 face) during the curing steps.
The tool defines two surface element sets that together form the contact surface with the
composite. These surfaces are referenced by the *Surface card in the assembly.
*Elset, elset=_tool-surface_S4, internal
<element_numbers>
*Elset, elset=_tool-surface_S6, internal
<element_numbers>
| Surface Set | Face | Description |
|---|---|---|
_tool-surface_S4 | S4 | Tool face 4 (one side of the L-bracket) |
_tool-surface_S6 | S6 | Tool face 6 (other side of the L-bracket) |
The two element sets are combined into a single surface in the assembly:
*Surface, type=ELEMENT, name=tool-surface
_tool-surface_S4, S4
_tool-surface_S6, S6
tool-surfacecom-surface (slave surface)The S4 and S6 faces correspond to the two planar faces of the L-shaped mold that contact the two arms of the L-shaped composite bracket.
The tool part is instantiated in the assembly alongside the composite part.
*Assembly, name=Assembly
*Instance, name=tool-1, part=tool
<node/element translations if needed>
*End Instance
*Instance, name=P8-1, part=P8
*End Instance
| Instance | Part | Description |
|---|---|---|
tool-1 | tool | Mold instance in the assembly |
P8-1 | P8 | Composite instance in the assembly |
When referencing nodes or elements in the assembly context, use the instance prefix:
tool-1.54P8-1.1The tool part's node numbering starts from 1, completely independent from the composite part. This means both parts can have a node 1, node 2, etc.
Per-part parsing: When reading the INP file, parse each *Part block separately.
Reset the node and element counters at each *Part boundary.
Assembly references: In the assembly section, nodes and elements are referenced
with the instance prefix (e.g., tool-1.54 or P8-1.3025). The prefix distinguishes
which part the node belongs to.
Set definitions: Sets defined inside a *Part block use local numbering. Sets
defined in the *Assembly block use instance-prefixed numbering.
The tool has a reference node (node 54) used for the springback constraint:
# Inside tool Part
*Node
54, <x>, <y>, <z>
# In Assembly, as part of Set-2
*Nset, nset=Set-2, instance=tool-1
54,
Global node numbering: Do not assume node IDs are unique across parts. Both tool and P8 start from node 1. Always use instance prefixes in the assembly context.
Surface face selection: The S4 and S6 faces must correspond to the actual mold faces that contact the composite. If the mold geometry is modified, verify that the face labels still point to the correct contact faces.
Mold extension: The mold must extend beyond the composite to maintain contact coverage during thermal expansion. If the mold is too small, the contact pair may separate prematurely.
Material assignment: The tool section must reference material=TOOL. If the
material name is misspelled or the *Material, name=TOOL card is missing, Abaqus
will error.
Thermal expansion: The tool's thermal expansion coefficient (2.52e-05) affects
contact pressure during temperature changes. Do not remove the *Expansion card
even if the tool is treated as rigid-like.
Element type: The tool uses C3D8R (reduced integration), while the composite uses C3D8 (full integration). Do not mix these up when editing the INP file.
