I want to assemble 2D shell (elliptical crack) to 3D plate. Abaqus software shows this error:
"part dimensionality does not match the dimensionality of the existing instances"
How can I assemble these parts together. I attach the picture which I want to model. would you please help me to assemble these parts. If you I have other solutions I would be happy to hear from you.
Thanks

Shells are usually more than 2D, but of course may degenerate in a plate which "has 2D geometry" but 3D response.
It may helps you.
In what phase of modelisation you are getting the error message?
If it is at the assembly. the broblem is 100% not related to FEM.
Hi Jamaleddin,
I've analysed this kind of FE models and also seen it before in some journal papers.
I recommend you not to use the shell elements on a 3D model, because it causes some errors in your results and the results will not be accurate any more!
maybe its better to use a 3D thin layer model instead of using the shell model.
Best of luck
