Error: Negative Jacobian detected during domain initialization

[tomisinajayi]

Hello,

I am having trouble running my structural mechanics model. It keeps giving me this domain initialization error and also lists specific elements that have negative jacobians. I have tried finding the elements and deleting them from my model; I've done it for several elements but it is still giving me the same error. I have also tried using nodal boundary conditions to keep the balloon in place as I apply pressure to stabilize the model. What can I do to fix it, please? I have attached my model also.
