Hi, i’m sukyung yoon

I am performing a plate analysis using the attached ini file.  
The analysis runs successfully, but when I apply tavg for w, an error occurs, and the calculation does not proceed. How can I resolve this? My mesh is indeed 3-dimensional.

I encountered the same issue before but was unable to resolve it.

MPI_ABORT was invoked on rank 1 in communicator MPI_COMM_WORLD
with errorcode 1.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.

Looking at your `ini` file you have

```auto
[constants]
gamma = 1.2941
Pr = 0.72
Uin= 117.6730
Vin= 0.0000
w = 0.0 # <- Here
Pc = 61.650773
rhoc= 0.001440
mu = 1.370e-5
cpTref =230401
cpTs = 187359.12

```

You never use this, but its name clashes with that of a primitive variable. Remove it and everything will be fine.
