@Mania 怀疑fft变换时参数选错了,OF不大可能错,因为你说之前的都没问题。

RE: pimpleFoam with komegaSST results in error
@李东岳 确实如李老师所说,将固定壁面边界条件Omega的值设置为1e-6后,能算了!!!

RE: pimpleFoam with komegaSST results in error
@李东岳 谢谢李老师!我估计是边界条件的事,有些边界条件用的fixedValue,0,但是我改为10e-6后仍旧报错,我再试试。ps:帖子用的ubuntu系统,没中文输入法,无奈只能用英文发帖了

pimpleFoam with komegaSST results in error
The error is as follows. However, if I input command "unset FOAM_SIGFPE" before "pimpleFoam", everything is OK. the OpenFOAM could run as usual. Could anybody help me for this stupid question?

RE: 正弦来流边界算例的后处理出现错误,求解决
就是renumberMesh后会重新生成一套网格数据,之前的还有个0文件夹网格数据。reconstructPar后,你将0文件夹删掉,再用paraFoam打开试试

RE: 正弦来流边界算例的后处理出现错误,求解决
是不是计算之前renumberMesh操作了?你只把renumberMesh后的网格和计算数据放一起,之前的不要放到一个目录里面,这样再用paraFoam打开试试。
我怀疑是乱码了
