1. After applying bias voltage for the comb drive, I cannot choose the boundaries to fix. It says that the boundaries I chose are not applicable. 2. When I try to compute, there has been an error saying that the mass matrix is zero. I think this may be because of the boundary probl...
The node Free is a boundary condition that allows all boundaries to move freely without a constraint or load. The node Initial Values is used for specifying initial displacement and velocity values for a nonlinear or transient analysis (not applicable in this case). The default physics nodes ...
However, a number of further enhancements of the new model are conceivable as a follow-up such as additional boundary conditions for water vapour or swelling into free space.下载 Paper_Kroehn_Fromme.pdf - 1.06MB Kröhn_6121_poster.pdf - 2.51MB ...
In COMSOL Multiphysics®, micromechanics-based homogenization is performed using theCell Periodicitynode in theSolid Mechanicsinterface. It has two different boundary conditions,PeriodicandHomogeneous. ThePeriodicboundary condition is applicable to the periodic materials and needs an RUC material subvolume. ...
there are some small differences in the boundary conditions. There are so-calledLumped Portand Lumped Element boundary conditions, applicable for microwave device modeling, which are solely part of the RF Module. Also keep in mind that only the Wave Optics Module contains the beam envelopes formula...

In any rotating magnetic machine, there are two parts: the stator and the rotor ,separated by an air gap enabling the rotor’s rotation. The Rotating Machinery,Magnetic interface uses the moving mesh approach to model this rotation, as the finite element method does not support rotations.
while the whole assembly is heated up from the initial room temperature. The criterion for initiation of adhesion is selected so that the temperature at the contact boundary should exceed 365 K. The geometry and boundary conditions are highlighted in the following set of figures, along with the ...
TheDeformed Geometryinterface is most applicable for modeling fluid, or free space, domains. If applied to a solid domain, a deformation of the boundary corresponds to a material addition or removal along that boundary. A change in the total volume of the domain implies that mass is being adde...
