Non-ideal weak constraints in V4.1

Please login with a confirmed email address before reporting spam

Hi

How can I implement the NON-IDEAL type weak constraint for the moving mesh ALE module in COMSOL 4.1? I could find only Bidirectional and User defined for the "prescribed deformation" case??

Many thanks

Tushar

Hi

the user type allow you to define at will

To better understand, take a "solid" structure apply a Prescribed Displacement boundary condition with values (a,b,c) for (x,y,z), select weak expression,. turn on the equations (preferences) then look at these equations in bidirectional and in unidirectional.

Learn the subtle differences ;), then apply that to your "user defined" ALE boundary conditions

Good luck
