OpenFOAM在集群上并行计算提示计算节点名称不规范

[Wust.liao]

在学校的集群上装好OpenFOAM后发现只能单核计算，不能并行计算，报错如下：
While trying to create a regular expression of the node names
used in this application, the regex parser has detected the
presence of an illegal character in the following node name:

node: hpc_cn09

Node names must be composed of a combination of ascii letters,
digits, dots, and the hyphen ('-') character. See the following
for an explanation:

https://en.wikipedia.org/wiki/Hostname

Please correct the error and try again.
估计是计算节点名称“ hpc_cn09”不能有下划线吧？但是要改集群的名称太不现实了，请问有能不改名称的解决方法吗？

目前也不确定是openMPI的问题还是OpenFOAM太挑剔，所以各位使用集群计算的老师同学们，能不能看看你们集群的hostname是不是有下划线的，能让我定位一下问题的位置。
