|
||||
|
||||
## 当前对比结果
|
||||
|
||||
默认 comparison 使用 `0 -> 1e-5 s` 的短时域，目的是在数值误差扩散前检查初值、RHS 和局部耦合。
|
||||
默认 comparison 仍使用 `0 -> 1e-5 s` 的短时域，并已新增
|
||||
`dm1@pneumatic_69` 流量诊断。
|
||||
|
||||
当前已确认：
|
||||
本轮确认原最大偏差的主因不是 PNL0001 Darcy 阻力，而是 8 个
|
||||
`PNVO001` 在 Python 中被固定为 `opening=1`，忽略了各自的
|
||||
`STEP0` 控制。AMESim baseline 显示 `step_8..15` 均在
|
||||
`t=0.04 s` 从 0 跳到 1，对应 PNVO 在此前保持关闭。
|
||||
|
||||
- 最大绝对误差路径是 `press@pn_c1_8`。
|
||||
- 初值已对齐：Python 约 `-1300 Pa`，AMESim 约 `-1300 Pa`。
|
||||
- `t=1e-5 s` 时 Python 约 `-1290.75976 Pa`，AMESim 约 `-1299.98825 Pa`，末值绝对误差约 `9.22849 Pa`。
|
||||
- `pn_c1_8` 的边界体积功只有约 `0.026 W`，端口焓流约 `32722 W`；当前偏差主要不像是活塞体积功导致。
|
||||
接入 STEP0 控制后的默认短时对比：
|
||||
|
||||
这表明 132 状态仿真链路已经能够暴露真实偏差，但 PNL0001、节点流量、孔口或 PNCH012 方程仍需数值标定，尚不能声称已经达到 AMESim parity。
|
||||
- `press@pn_c1_8` 末值误差从约 `9.22849 Pa` 降为
|
||||
`0.0117249 Pa`。
|
||||
- Python `dm1@pneumatic_69` 末值约
|
||||
`-4.97737e-7 g/s`，AMESim 线性插值约
|
||||
`-2.05425e-6 g/s`。
|
||||
- canonical chamber-to-line flow 定义为
|
||||
`-dm1 * 1e-3`，因此两者分别约为
|
||||
`4.97737e-10 kg/s` 和 `2.05425e-9 kg/s`，绝对误差约
|
||||
`1.55652e-9 kg/s`。
|
||||
- AMESim 首个 `0.01 s` 区间的 `mgas1@pn_c1_8` 有限差分约
|
||||
`-9.86349e-7 kg/s`；用该区间首末 `dm1` 做梯形平均得到的
|
||||
chamber 质量变化率约 `-1.02713e-6 kg/s`，符号和量级一致。
|
||||
|
||||
当前剩余 `1e-5 s` 误差不能直接解释为物理方程误差：AMESim
|
||||
baseline 只按 `0.01 s` 保存，而 comparison 在首个保存区间内做
|
||||
线性插值；位移、体积和压力的初始响应并不一定是线性的。
|
||||
|
||||
## 下一步
|
||||
|
||||
下一步只围绕当前最大偏差推进：
|
||||
1. 增加 AMESim 保存时刻对齐的诊断，优先比较事件前的
|
||||
`t=0.01 s`，避免把 `1e-5 s` 线性插值误差当成物理偏差。
|
||||
2. 导出 `xv@pn_morifice_1` 和 `dm2@pn_morifice_1`，检查
|
||||
`t=0.04 -> 0.05 s` 开启窗口的 PNVO 流量及事件传播。
|
||||
3. 在控制时序对齐后，再判断是否需要校准 PNVO 流量系数、
|
||||
`pneumatic_69` 的 PNL0001 阻力或 PNCH012 能量方程。
|
||||
4. 继续保留 `press@pn_c1_8`、`dm1@pneumatic_69` 和 chamber
|
||||
RHS breakdown 作为同一条诊断链。
|
||||
|
||||
1. 导出 Python 的 `p4_port3_remote_chamber_to_line_flow`。
|
||||
2. 与 AMESim 的 `dm1@pneumatic_69` 比较，先做 `g/s -> kg/s` 单位转换并确认符号方向。
|
||||
3. 比较 `t=0` 和 `t=1e-5 s`，并用 `mgas1@pn_c1_8` 的有限差分交叉验证质量导数。
|
||||
4. 若流量偏差明显，检查 `pneumatic_69` 的 PNL0001 `resistance_mass_flow`、参数和 `pnnode4_16` 节点平衡。
|
||||
5. 若流量吻合，再校准 PNCH012 焓流、氦气物性以及质量/能量到压力导数的换算。
|
||||
|
||||
`pn_c1_8` 的直接主线是 `pneumatic_69`。`pneumatic_96` 属于 `pn_node3_8 -> pn_general_chamber` 固定气室支路，不是本轮流量诊断对象。
|
||||
`pn_c1_8` 的直接主线是 `pneumatic_69`；`pneumatic_96`
|
||||
属于另一条固定气室支路，不是该诊断对象。
