OpenFOAM编译时内部编译器出错

[Afr1yne]

@李东岳 每次的报错还不一样，网格是从能用的那台电脑复制过来的，都是WSL2

[李东岳]

你测试不复制网格。直接纯WSL生成网格等一系列操作，正常么

[Afr1yne]

@李东岳 tutorials里面的都能跑
这也是报错之一，每次不一样

[李东岳]

不decomposePar能跑么

[Afr1yne]

@李东岳 单核不带温度内部场的codestream能跑

[李东岳]

所以能不能缩小到是decomposePar的问题？

[Afr1yne]

@李东岳 tutorials里面的decomposePar好使,在我的case里面不行，我把tutorials里的拿过来也不行

[李东岳]

你是复制的么 WSL下复制的么

[Afr1yne]

@李东岳 两台计算的电脑都是windows远程的，复制的路径是好电脑WSL2>好电脑windows>控制远程的电脑>坏电脑windows>坏电脑WSL2。然后网格我是用pointwise画的，本身就是windows的 我重新传了一下也没有用

[Afr1yne]

@李东岳 我只复制了0 constant system，里面都是数字啊 会有问题吗

[李东岳]

linux和windows的文件系统不一样 不知道复制的会不会有问题 不确定

[Afr1yne]

@李东岳 从300w网格换成30w网格 能分6然后报错，能不能跟内存或者是核心数的设置有关，但是WSL2的相关设置我都调过

[李东岳]

我看你之前报错是OSstream的错误。这个一般跟硬盘读写有关。比如文件满了可能报错。

最后一个图那个log基本啥都没说，判断不出来

[Afr1yne]

@李东岳 东岳老师这个空间应该没啥问题，硬盘读写这块也可能是WSL2的问题吧？

[Afr1yne]

@Afr1yne 用scotch是这个报错
simple是这个报错

[李东岳]

你重新用g9编译一下src/parallel那个库看看
