Why is a second TB command ignored? For example, in the input below, the
second TB command is an attempt to change TBOPT, but it is ignored.
------------
/prep7
TB,PIEZ,110 ! first TB command for Piezoelectric stress matrix[e]
MP,DENS,110,1780
mp,perx,110,7.522e-11
mp,pery,110,1.204e-10
mp,perz,110,9.735e-11
tb,piez,110,,,1 ! second TB comannd for Piezoelectric stress matrix [d]
Normal ANSYS functionality is to overwrite the previous specification as would
happen in the input below.
/prep7
et,1,186

The table data is complicated and it would be risky to just over-write certain entries. It is necessary to delete the existing table before respecifying the TB command as you are doing above. At 11.0 we have improved the documentation and added information to the warning message when the table is re-entered to let the user know that new input has not been used. |
