Hi Sir
I exporting the loads on the anybody spine.But the generated .xml file is only 2 kb and no load are showing in the file.Coding are given following-
AnyMechOutputFileForceExport FE_Out =
{
FileName = “Output\spineload.xml”;
UseRefFrameOnOff = On;
AnyRefFrame & ref1 = Main.HumanModel.BodyModel.Trunk.SegmentsThorax.ThoraxSeg.T12L1JntNode.localrefframe ;
AllSegmentsInStudyOnOff = Off;
XMLformatOnOff = On;
//AllSegmentsInStudyOnOff = Off;

  AnySeg &Thoraxseg =   Main.HumanModel.BodyModel.Trunk.SegmentsThorax.ThoraxSeg.T12L1JntNode;
  
};

Thanks.

Replace AnySeg &Thoraxseg = Main.HumanModel.BodyModel.Trunk.SegmentsThorax.Tho raxSeg.T12L1JntNode;

by

AnySeg &Thoraxseg = Main.HumanModel.BodyModel.Trunk.SegmentsThorax.Tho raxSeg;

Dear sir
We have only lumbar part of spine from ct data. So we only want to export loads on it instead of full spine. So where should i define anyrefnode?
Is it possible only export loads on half spine?
Thanks.

Mohit,

the best way would be to export forces for each segment of the lumbar spine in the segmental reference frame, apply converters and merge the files into one analysis.

Kind regards,
Pavel

Dear Sir,

Kindly confirm if i am correctly getting your point. From your last reply what I understand is, I take a single vertebra mesh and get loads applied from any2fe convertor, repeat the process for the remaining vertebrae and get the loads applied on individual vertebrae.
after that I import the output meshes generated from convertor in abaqus along with discs (artificially created in 3-matic), apply contacts between the vertebra’s, disc and perform the analysis.

Yes, roughly.

There will be a few tricks on the way, but it is probably best for you to start working and resolve smaller problems one by one.

Kind regards,
