Time integration

Please login with a confirmed email address before reporting spam

Hello

I would like to compute the acoustic velocity in time dependent domain. For this, I resolve the acoustic equation and I obtain the acceleration. The velocity is equal to the time integral of the acceleration. I used the "Global equation" for the computation, I fund :"Error 6250 : failed to evaluate variable Jacobian".

does anyone have a solution ?

Thank you everyone.
