Coming soon!
• Get the Vector Potential solution for different time points from OPRA.
• Apply the 1/R field.
• Calculate the B’s and Bdots and induce eddy currents.
• Convert it into a structural model, read the forces and run a stress pass.
What to expect…
• Ran a stress pass with a Bdot of 0.7 T/s and a vertical B of 0.1T.
