Output displacements at each node
« on: July 16, 2014, 11:56:24 AM »
Hi,

I am trying to output the displacement data at each node but what I get back is only zeroes for both outputs. The procedure that I followed was:

1.   I modified the input that I had used for the serial version by replacing the solution commands with

BATCh
  GRAPh,,2
  OUTDomains,AIJ,1
END

2. Initially, I ran feap to make the two partition inputs ixxx_0001 and ixxx_0002
3. In the serial version I used user defined material and I saw that this information wasn’t included in the two partitions so I modified the two inputs to have the user defined material properties correctly.
4. at the solve.xxx I wrote the

BATCH
PROP,,1,2
END



BATCh
PETSc ON
  NOPRint
  DT,,001
  TRANsient NEWMark
  INITIAL
  TANG
  LOOP,print, 1000
   LOOP,time,1
    TIME
      LOOP,Newton,1000
   FORM
   SOLV
      NEXT,Newton
    NEXT,time
    DISP,all
    STRE,all
    REAC,all
  NEXT,print
  SAVE

END

STOP
5. I ran for the second time feap giving as input the xxx_0001 and I got back two log files and two outputs (lxxx_0001,lxxx_0002, Oxxx_0001,Oxxx_0002)

When I checked the output files ( Oxxx_0001,Oxxx_0002) I saw that the stresses and reactions are ok but the displacements are all zero and I don’t understand what I did wrong.

Thank you very much for your help

What do you mean by: "5. I ran for the second time feap giving as input the xxx_0001" ?
Also it is not very clear to me what you are trying to do with the "print" loop, can you explain the goal of this loop?
