Follow up on convergence failure on continental extension model

Hi,
@jbnaliboff This is update regarding 22nd Monday regular user meeting , where i showed a continental extension model with GMG solver that failed to converge at the onset of continental breakup. The problem solved after adding diffusion to the top surface as suggested :slight_smile: .

Best,
Chameera

Thanks for the udpate @chameerasilva and glad to hear this solved the issue!
