这样的LOG文件表示什么意思
<P><FONT face=宋体>我做了个结构和声场耦合分析的例子，现在分析不出结果，LOG文件中提示如下，不知道什么意思，有人知道请帮忙看看<BR>Computing projected COUPLING matrix <BR> Verification of projected COUPLING matrix <BR> FLUID ROW 1 OF PROJECTED COUPLING MATRIX IS ZERO ! <BR> Check for rigid body modes in modal basis ! <BR> FLUID ROW 2 OF PROJECTED COUPLING MATRIX IS ZERO ! <BR> Check for rigid body modes in modal basis ! <BR> FLUID ROW 3 OF PROJECTED COUPLING MATRIX IS ZERO ! <BR> Check for rigid body modes in modal basis ! <BR> FLUID ROW 4 OF PROJECTED COUPLING MATRIX IS ZERO ! <BR> Check for rigid body modes in modal basis ! <BR> FLUID ROW 5 OF PROJECTED COUPLING MATRIX IS ZERO ! <BR> Check for rigid body modes in modal basis ! <BR> FLUID ROW 6 OF PROJECTED COUPLING MATRIX IS ZERO ! <BR> Check for rigid body modes in modal basis ! <BR> FLUID ROW 7 OF PROJECTED COUPLING MATRIX IS ZERO ! <BR> Check for rigid body modes in modal basis ! <BR> FLUID ROW 8 OF PROJECTED COUPLING MATRIX IS ZERO ! <BR> Check for rigid body modes in modal basis ! <BR> FLUID ROW 9 OF PROJECTED COUPLING MATRIX IS ZERO ! <BR> Check for rigid body modes in modal basis ! <BR> FLUID ROW 10 OF PROJECTED COUPLING MATRIX IS ZERO ! <BR> Check for rigid body modes in modal basis ! <BR> STRUCTURE COL 1 OF PROJECTED COUPLING MATRIX IS ZERO ! <BR> Check for rigid body modes in modal basis ! <BR> STRUCTURE COL 2 OF PROJECTED COUPLING MATRIX IS ZERO ! <BR> Check for rigid body modes in modal basis ! <BR> STRUCTURE COL 3 OF PROJECTED COUPLING MATRIX IS ZERO ! <BR> Check for rigid body modes in modal basis ! <BR> STRUCTURE COL 4 OF PROJECTED COUPLING MATRIX IS ZERO ! <BR> Check for rigid body modes in modal basis ! <BR> STRUCTURE COL 5 OF PROJECTED COUPLING MATRIX IS ZERO ! <BR> Check for rigid body modes in modal basis ! <BR> STRUCTURE COL 6 OF PROJECTED COUPLING MATRIX IS ZERO ! <BR> Check for rigid body modes in modal basis ! <BR> STRUCTURE COL 7 OF PROJECTED COUPLING MATRIX IS ZERO ! <BR> Check for rigid body modes in modal basis ! <BR> STRUCTURE COL 8 OF PROJECTED COUPLING MATRIX IS ZERO ! <BR> Check for rigid body modes in modal basis ! <BR> STRUCTURE COL 9 OF PROJECTED COUPLING MATRIX IS ZERO ! <BR> Check for rigid body modes in modal basis ! <BR> STRUCTURE COL 10 OF PROJECTED COUPLING MATRIX IS ZERO ! <BR> Check for rigid body modes in modal basis ! <BR> CPU Stats --- Delta:0:00:00 ( 0.00)Total:0:05:53 ( 352.95) <BR> <BR> Occupied space: 2341837 words( 23.42 %) </FONT></P>
