Title: error when different PROPs are defined
Post by: aza on May 07, 2019, 06:29:52 AM

Dear FEAP users,

in the attached input file, a 2D rectangle with prescribed displacements in x- and y-direction is defined. The upper right corner should have a displacement of (0.05, 0.025). This works as long as only one proportional load is defined. If a second one is defined, even without being used, the resulting displacement is (0.10, 0.025), as can be seen at the end of the output file.

Is that a known bug in FEAP version 8.2? I also tested it in FEAPpv 4.1, where the same problem occurs.
I would appreciate if someone had a suggestion to solve the problem.

There is a bug.  The eprop is not adding the b.c. together so the node 9 loses the x-prop number. 

in the subroutine 'pedgin.f' in the ./program directory under the 'Set edge proportional load numbers'  delete the statement

       etype = 'set'

before the call to pedges.

This should not be there.
