Changing nodes from a .odb file
Changing nodes from a .odb file
(OP)
Hi all,
I know tat we can take the nodal coordinates of a model from the .odb file. I would like to know if there anyway of changing the coordinates of the model in the .odb file to be re-run in abother analysis.
Thanks

RE: Changing nodes from a .odb file
You cannot remove or change any information inside odb file.
You can only read or add new information.
However it is possible to create new odb file where you can copy
all information expect nodes coordinates and create new coordinates for the nodes.
Unfortunately there is no tool to do it and whole process has to be done with scripting.
It could be quite challenge to create script to copy all necessary information.

I would really appreciate some input from others, thanks.
RE: Changing nodes from a .odb file
I would like to keep this node numbers matching between the .inp file and .odb file, thanks.
RE: Changing nodes from a .odb file
You can save your inputdeck without instances and assembly.
Model -> Edit Attributes -> Do not use parts and assemblies in input files
Then nodes/elements numbering between inputdeck and odb should be the same.

RE: Changing nodes from a .odb file
Do you know if there is any other way? I tried making the parts independent as instances and meshed the parts in the assembly modules, this was better, but some of the nodes number between the .inp file and .odb file were still not matching.
I would really appreciate any further help and input, thank-you
