Shear on plate element

[Enginit]

Hi all,
I am using FEAP v8.4 and simulate a simple plate problem as the input file.
When I export the plate shear force, all are zero. I think I may make a wrong input file.
I tried to read the manual and examples but there is no hint showing how to turn on shear in the plate.
Any suggestion would be really appreciated.
Best regards

I reproduced the error.  We'll have a look and get back to you with the fix.

[Prof. R.L. Taylor]

There is an error in subroutine ./elements/plate2t.f around line 347  the statements read:

          tt(1) =  hh(1,1)*gamm(1) + hh(1,2)*gamm(2)
          tt(2) =  hh(2,1)*gamm(1) + hh(2,2)*gamm(2)

they should read
          tt(4) =  hh(1,1)*gamm(1) + hh(1,2)*gamm(2)
          tt(5) =  hh(2,1)*gamm(1) + hh(2,2)*gamm(2)

This occurs in ver8.4, ver8.5, ver8.6.  It does not occur for the quadrilateral element.

The interpolation for element shear values may not be very accurate

Dear Prof. Taylor and Prof. Govindjee,
Thank you for your kind support.
I tried with Prof. Taylor's comment and now there are some shear values now.
Best regards,
