3. Solve the update geometry using the solution of the previous simulation as initial condition; The problem is that I cannot do the last step, I get this message "Messages: Wrong number of dofs in property init". I guess it happened because modifying the geometry changes also the number ...
In the Stationary study step, we create an auxiliary sweep of “visc_ramp” for values of 1000, 100, 10, and 1. The auxiliary sweep will find a solution for the first value of “visc_ramp” (1000) and use this solution as the initial condition for solving the next value of “visc_...
• If the time derivative of a state variable appears somewhere in the model during a time-dependent solution, the state variable needs an initial condition. Models that contain second time derivatives also require an initial value for the first time derivatives of the state variables. Set these...
often, a becomes only slightly negative (due to approximations in the solution process)。 then, a possible solution is to use (a+e)b, where e is a small constant。 another remedy is to use abs(a)b. if you do want to h 28、ave a complex number ab, go to the advanced tab of ...
After the ramp, the DC bias conditions have been calculated properly, and you can use this solution as initial condition for the transient simulation. 4 | INDUCTOR IN AN AMPLIFIER CIRCUIT Solved with COMSOL Multiphysics 5.0 Using a global variables plot, you can easily plot input signal, output...
Open circuit induced voltages in three-phase stator multi-turn windings as a function of time. Summary The existingRotating Machinery, Magneticinterface is the solution for modeling rotating machines. However, when modeling linear or tubular machines, it is more appropriate to use theMagnetic Fieldsan...
properly and this solution can be used as initial condition for the transient simulation. After 0.2 ms the magnetic field and contour lines of the vector potential should look like Figure 1 below. Figure 1: Magnetic flux density (color) after the bias point calculation. amplifier_and_inductor...
The advantages of porous structures DRCers include: 1) they can effectively scatter light between the interface of polymer and air; 2) they can be fabricated by solution-based and scalable methods, such as freeze-drying, phase separation, or electrospinning [41,42] and; 3) their ability to ...
