Combining parametric and auxiliary sweep

Please login with a confirmed email address before reporting spam

Hello everybody,

I am having some troubles with a quite simple simulation.

I must simulate the behaviour of a thin membrane which is stretched by means of a displacement applied to one of its ends. I would like to sweep increasing values of the applied displacement (let's say, from 0 to 2 mm with a step of 0.2 mm) but I also have to evaluate the influence of geometric parameters (such as the thickness of the membrane, and the dimensions of some other features on it) on the results.

I know that a sweep involving changes in the geometry requires a Parametric Sweep, but to improve the convergence of the simulation I would like to set a "continuation solver" for the displacement parameter. As far as I have understood, the continuation solver can be used only with an Auxiliary Sweep.

Therefore, I would like to know if it possible to combine a Parametric sweep (concerning the geometric parameters) with an auxiliary one (containing the displacement only), or if there is any other way to efficiently tackle this problem. All my attempts have failed (I have tried to put all the parameters in the auxilary sweep, setting the continuation for the displacement, but it did not work since the geometry is actually always the same).

I thank you in advance for your help.

Alberto
