Dear Forum members,
I´m trying to generate the mnf file (modal neutral file) of a twist beam rear suspension system (the mnf file will be used later to create an ADAMS-CAR model)
I generated the twist beam FE model using ABAQUS CAE (I´m using an ABAQUS 6.14-1 version):
1) From direct measurements (CMM) I generated the geometry using CAD software (I generated only half of the model).
2) Then I imported the geometry into ABAQUS and generated the mesh for the half model.
3) In order to obtain a perfectly symetric mesh I made this mesh (the half model mesh) orphan and then I created a symetric copy of it.
4) Then I placed both orphan meshes together in the assembly module, merged them and then obtained a full twist beam orphan mesh
After applying all necesary constraints I generated the input file required to generate the mnf file. I followed all the steps defined in the Abaqus documentation to create and run the analysis from the command line.
When I run the analysis I get an error message: " ***ERROR: SYSTEM ERROR IN SUBSTRUCTURE GENERATE PROCEDURE - NODE 25609 IS NOT PART OF THE RETAINED NODE."
I get this error message even tough the node is defined as a retained node.
I can´t find a way to solve this problem, I did some research but I couldn´t find any solutions.
I would highly appreciate any help you could provide.
