openFoamの計算実行について

[netu]

はじめまして。

openFoam を初めたばかりのものなのですが、

今までは計算できていたのに下記の表記がでてきてしまい計算が実行されなくなってしまいました。

もしわかる方がいらっしゃいましたらお教えいただけないでしょうか。

// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // /opt/openfoam8/bin/foamExec buoyantBoussinesqSimpleFoam -parallel | tee  log

----------------------------------------------------------------------------

Open MPI has detected that a parameter given to a command line

option does not match the expected format:

  Option: np

  Param:  /*--------------------------------*-

This is frequently caused by omitting to provide the parameter

to an option that requires one. Please check the command line and try again.

どういう方法でOpenFOAMを実行しているのか書かれていないので原因はわかりませんが、
エラーメッセージ自体は mpirun の np オプションの設定がおかしいというもののように見えます。
例えば mpirun を使って buoyantBoussinesqSimpleFoam を 6 並列で実行する場合は次のようにします。

「mpirun -np 6 buoyantBoussinesqSimpleFoam -parallel」

また、decomposeParDict が正しく書かれているかも確認した方が良いかもしれません。

ありがとうございます

1度試してみます

mpirun -np 4 buoyantBoussinesqSimpleFoam -parallel

上記のようにnpオプションを設定したところ、下記のようなエラーが出てきてしまうのですが、

分かる方がいらっしゃいましたらお教えいただけないでしょうか。

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.
