PFC FISHTank (fistPkg) Standard Test Framework

Use this skill to understand and externally reuse Itasca PFC 5.0 FISHTank fistPkg26. Treat it as a PFC 5.0 dependency without requiring a particular PFC5.0 subversion. Its files remain outside this skills package; the complete asphalt parent is pfc5-asphalt-workflow.

When To Use

Use this skill when the user needs to:

• Understand what fistPkg (FISHTank) provides and how its directories are laid out.
• Reuse the standard compression / diametral-compression / direct-tension test framework (ct/dc/tt).
• Generate a material specimen with MatGen (linear, contact-bonded, parallel-bonded, flat-jointed, Hill).
• Extend the diametral-compression framework with custom loading heads (e.g. curved heads for a Marshall-type test per JTG T0709).
• Locate the FISH tools (ck/ct/dc/tt/ft/hl) and the Hill DLL installation requirement.

Do NOT use this skill for asphalt-specific modeling choices — those are in pfc-asphalt-mixture, pfc-burger-viscoelastic, pfc-marshall-test, pfc-rutting-test.

Required Inputs

Ask for these if missing:

• Target material type: linear / contact-bonded / parallel-bonded / flat-jointed / Hill (3D UDM).
• Target test: compression (confined/unconfined/uniaxial) / diametral-compression / direct-tension.
• PFC2D or PFC3D 5.0. If another major version is requested, stop: it is outside this package.
• Whether the Hill UDM DLL is needed (3D Hill material only).
• Legal <FISTPKG_ROOT> and a PFC2D/PFC3D 5.0 runtime.

fistPkg Capabilities

• Material genesis: linear, contact-bonded, parallel-bonded, flat-jointed, and user-defined (3D Hill) materials in polyaxial/cylindrical/spherical vessels; grains as balls or clumps.
• Material tests: compression (confined, unconfined, uniaxial strain), diametral-compression, direct-tension.
• Microstructural monitoring: grain-size distribution, microstructural plots, crack monitoring for bonded materials.

FISH Tool Map

工具	用途
ft.fis	FISHTank 主库（核心工具函数：墙-颗粒行为、平衡等）
ck.fis	检查/微观结构监测（级配、配位数等）
ct.fis	压缩试验（confined/unconfined/uniaxial）
dc.fis	劈裂/间接拉伸试验（diametral compression）——马歇尔试验基座
tt.fis	直接拉伸试验
hl.p3fis + udm_hl.p3fis	Hill 用户自定义接触模型（3D）
contactmodelmechanical3dhill005_64.dll	Hill 模型 DLL（需安装到插件目录）

Workflow

1. Run the self-contained checker: scripts/check_fistpkg.py "<FISTPKG_ROOT>".
2. 选材料类型（linear/contact-bonded/parallel-bonded/flat-jointed/Hill）。
3. 按官方 README，把 ExampleProjects/fistSrc 与一个 MatGen-X 复制到 私有案例目录；先运行未修改的基线。
4. 生成完成后运行对应试验（CompTest/DiamCompTest/TenTest）。
5. 自定义压头时，以 _dcMakeWalls 为最小几何钩子，同时审计墙 ID、 轴向、接触、平滑、力/位移、终止和后处理。

Working Rules

• fistPkg is PFC 5.0 — use PFC 5.0 syntax directly and do not generate another major-version case from this skill.
• The Hill UDM requires copying the DLL to PFC500\exe64\plugins\contactmodelmechanical3D (PFC 5.0 layout).
• Do NOT vendor Itasca's fistPkg source into a public MIT repo — extract usage patterns and command templates only, cite the package as external.
• Reuse the staged, saved-state style (MatGen → CompTest/DiamCompTest/TenTest) for reproducibility.
• Replacing _dcMakeWalls is necessary for custom heads but is not by itself a complete Marshall validation.

Output Contract

A complete fistPkg handoff should include:

• Material type and vessel geometry chosen, test type selected.
• Which FISH tools (ck/ct/dc/tt/ft) are needed and how they are called.
• The extension point used (e.g. _dcMakeWalls for custom heads).
• Any DLL/plugin installation note.
• A note that the case targets PFC2D/PFC3D 5.0; route other major versions outside this skill.
• The checker result, baseline run result, copied-file manifest and runtime_validated status.
