以ANSYS的.cdb格式导入SYSNOISE出现网格变形
在ANSYS中建模，以.cdb格式导入SYSNOISE网格变形厉害，不知道为什么<BR>LOG文件中提示 CHECKING DEGENERATED ELEMENTS <BR> ELEMENT 1 IS DEGENERATED :TRANSFORMED FROM QUAD4 TO TRIA3 <BR> ELEMENT 1 IS DEGENERATED :TRANSFORMED FROM QUAD4 TO TRIA3 <BR> ELEMENT 1 IS DEGENERATED :TRANSFORMED FROM QUAD4 TO TRIA3 <BR> ELEMENT 1 IS DEGENERATED :TRANSFORMED FROM QUAD4 TO TRIA3 <BR> ELEMENT 1 IS DEGENERATED :TRANSFORMED FROM QUAD4 TO TRIA3 <BR> ELEMENT 1 IS DEGENERATED :TRANSFORMED FROM QUAD4 TO TRIA3 <BR> ELEMENT 1 IS DEGENERATED :TRANSFORMED FROM QUAD4 TO TRIA3 <BR> ELEMENT 1 IS DEGENERATED :TRANSFORMED FROM QUAD4 TO TRIA3 <BR> ELEMENT 1 IS DEGENERATED :TRANSFORMED FROM QUAD4 TO TRIA3 <BR> ELEMENT 1 IS DEGENERATED :TRANSFORMED FROM QUAD4 TO TRIA3 <BR> ELEMENT 1 IS DEGENERATED :TRANSFORMED FROM QUAD4 TO TRIA3 <BR> ELEMENT 1 IS DEGENERATED :TRANSFORMED FROM QUAD4 TO TRIA3 <BR> MINIMUM ELEMENT EDGE RATIO (min/max)= 6.65190E-02 AT ELEMENT 521 <BR> MAXIMUM ELEMENT EDGE LENGTH= 1.50333E+00 AT ELEMENT 521 <BR> NO SUPERIMPOSED NODES WITH TOLERANCE=1.00000E-06 <BR> NO ISOLATED NODES <BR> CHECKING ELEMENT TOPOLOGY AND DISTORTION <BR> ELEMENTS 1 AND 1 ARE SUPERIMPOSED.
