[求助] FLUENT单机多核并行运算导入udf之后，初始化报错，Received signal SIGSEGV 已有1人参与

用FLUENT的圆管内超临界水流动传热，采用SST模型，用udf在material物性设置里面定义超临界水的物性随温度的变化，然后初始化的时候报错，错误信息如下：
==============================================================================

Node 4: Process 19756: Received signal SIGSEGV.

==============================================================================
MPI Application rank 0 exited before MPI_Finalize() with status 2
The fl process could not be started.
下面是我的udf代码，udf直接在记事本里写的，然后把扩展名改成.c ，请问是udf的问题，还是我别的什么地方弄错了？PS，我串行运算的时候也报错Error:  received a fatal signal (Segmentation fault).
Error Object: #f，求大神指教！
