Title: loading at 2 different times?
Post by: aleximos on August 19, 2012, 07:33:15 AM

LOAD PROP command seems not to work in parfeap :-[
LOAD PROP 1
....

LOAD PROP 2
.....

LOAD END
Can sb suggest me of another way to impose 2 loads at 2 different times?

The problem is that the subroutine uoutdom (in the file parefeap/pmacr7.F) was written before the introduction of load groups.

You could probably add the output of the load groups without too much difficulty to this subroutine or if you explain better what type of loading you would like to apply, it may be possible to do it without using load groups [rather using the FPRO and associated commands].

I'm trying to apply in the beginning a shear displacement and later only tensile displacement.
I'm attaching you also the files

You can do this easily with the EPROportional command (see page 48 of the manual); i.e. the use of load groups is not needed for such a simple case.

EDISP
1   0 us 0  0
2 95 0  ut  0

EPRO
1   0  1 0 0
2 95  0 2 0

If you are using a late version of the program consider using LOAD groups.  This is an easy way to apply load sets that have different time behavior.  See current user manual for details.
