[Yade-users] [Question #701564]: Install yade in the centos7 system. After executing the make install command, an error is reported when compiling FlowEngine.cpp
New question #701564 on Yade:
https://answers.launchpad.net/yade/+question/701564
Hi,everyone
I am compiling and installing yade in the centos7 system. Refer to [1].
After executing the make install command,some errors are reported when
compiling FlowEngine.cpp.
This seems to be related to the design of FlowEngine.cpp. itself . In
trunk-2022.01a\pkg\pfv, there are three FlowEngine related header files
(FlowEngine.hpp FlowEngine.hpp.in FlowEngine.ipp.in).
Please let me know if full file is required or if you find other errors in the
script.
Thanks in advance for your help！

In previous simulations, the axial strain when the failure condition is reached is very small (0.03 or less),but this time, when the axial strain reaches 0.15 or more, it still does not reach my failure condition (the axial stress does not decrease)..
