The OpenSees Community

Hi all,

I noticed that when OpenSeesSP is used, node reaction recorder does not record reactions at all the nodes using the following command:

recorder Node -file $dataDir/BaseRxnsDOF1.out -time -node 1 6 11 16 21 26 31 36 41 46 51 56 61 66 71 76 -dof 1 reaction

Reactions for some of the nodes are zero using above for np > 1. It is fine for np = 1. Similarly, the OpenSees manual states that drift recorder also does not work for np >1. So I was wondering which recorders do and do not work in parallel versions. Is there any other way to record reactions in OpenSeesSP with np>1?

Thanks.

that's a bug that needs to be fixed. i will need the script as it works for the few examples i have.

Thanks fmk. I sent you an email with the scripts.

Any thoughts fmk?

not a quick fix .. basically the reaction recorder is the 1 recorder where i need to add duplicates instead of throwing them away .. it means changing a few interfaces .. it is one of the last things i need to finish before i officially release the 2.4.4 version (a 5730 revision is being tested now, the revision with your fix will have a greater revision number)

Thanks fmk. Do you then think that adding up the bottom story element forces will give correct reaction for any number of processors (until the reaction recorder is fixed)?

yes.

Thanks.
