Hello everyone
I am trying to mesh and run a simulation of a bone with an implant in it. For inserting the implant into the bone, I used the combine feature to make the bone hollow for implant to be placed. After making the hollow bone, I inserted the implant by making mates with the hollow space in the bone.
I have attached the file for your reference.
The problem is, while trying to perform a static analysis on this assembly by applying force on the implant. After meshing is done and it is trying to simulate, this error pops up.
And this is the snip of simulation study
How do I avoid this error and perform analysis without any problems? Please help me with this.
PS: The fixed geometry boundary has been applied arbitarily on the bone because this cad model of the bone has its surface broken into smaller bits. So there is no complete single surface I could apply fixed geometry condition to. I tried the knit surface feature, but it also shows errors.
Thank you for your help and time.
Regards

It is diffucult to tell what you are trying to learn/analyze with your simulation. You state why you applied the fixed
geometry as you did, but fixing it as high (as close to the load) as you did -- seems to imply that you are only
interested in the top 1/3 or 1/4 of the model, perhaps? If so, you may want to cut away the rest of the bone/model
and fix on the freshly cut face.
I'd wager the error is related the surface breaks ie the quality of your solid model.
Merged midside notes are a meshing problem of course.
Perhaps this is happening in an area of little interest that you could cut away (as above).
Otherwise, as stated in the Help section, Set the Jacobian Check (in Mesh Options) to At Nodes and use a higher
# of points.
