Hello,
I hope you are doing well.
I have a model in which I assigned a damper and spring. When I imported the model into FEBio Studio, I encountered a message indicating that the materials for two nodes (the nodes defining the damper and spring) are not assigned to any parts. I am unsure if this message is a warning and why it is occurring. Last year, I ran the model with the same syntax and did not receive this message.
Additionally, after running the model, I received a "Negative Jacobian Error" message, and I am not sure if it is related to the previous error message. I am unsure about the Negative Jacobian Error message as well. I have attached my model in this message.
I would appreciate your help with this matter.
Thank you very much for your response,
Kind regards,
Royan
