Topology optimization -error negative jacobian
Hello,
I am doing the topology optimization of a part with solid hexa elements. While running the optimization it shows that a particular element has zero or negative jacobian.
I masked that element seperately and modified the distance between the nodes so that the jacobian value is increased and again run the optimization.
Now it is showing that there is an error with node numbering sequence, I renumbered all nodes as well as elements. But the error persists.
How to resolve this.
The exact error is as follows
*** ERROR # 2502 ***
Element 27226 had incorrect node numbering sequence and needs renumbering.

Hi,
Generally by improving mesh quality it should run.Which version of Hypperworks you are using? (Student or full version)
If full version then share the updates information.

Hi Rahul,
It is a full version Hyperworks13.0.

Hi,
Can you renumber all node IDs in your model?
The error message says, the node numbering is wrong.
Check if renumbering helps or not.
