Re: Linear Elasticity: Normal Force depending on displacement?
Hi, If the finite element approximation is based on using piecewise polynomials of degree 2 or higher, the nonlinear elasticity solver could in principle be used for handling shells and plates. However, for very thin bodies the accuracy is expected to be far from optimal. There are certainly better ...
Re: ParStokes
Hi, The solutions of the standard NS solver and the ParStokes solver have been compared carefully for several problem setups (including the ISMIP-HOM benchmark cases for which reference results have also been published in the literature) and the solutions have generally been in good agreement. In ca...

Hi,
The revision r6362 contain an additional fix and may work better.

Re: MagnetoDynamics: Source current with StaticConduction, jfix
Hi, I hope that the revision 6355 eventually offers a fix to this issue. The observed convergence problem appears to be related to the part of computation where the user-specified source is computed to be divergence-free via applying the Helmholtz projection to the user-specified source. This comput...

Re: Linear Elasticity: Normal Force depending on displacement?
Hi,
I just committed a new version of ElasticSolve.src which should enable the use of all classic element types. I think the nonlinear elasticity is the only way to go if the change in the orientation of the surface force vector has to be taken into account.
Best regards,
Mika

Re: Finite Elasticity model
Hi, Concerning the RHS - the part DOT_PRODUCT(dBasisdx(p,:),Stress1(i,:)) corresponds to the integration of the inner product <-S(F_k),grad v)> where S(F_k) gives the first Piola-Kirchhoff stress in the current state with the deformation gradient F_k and v is the test function - the part DOT_PRODUCT...

Re: Creating a new Element (some guide lines, please)
Hi, I think there is a trick that enables using bodywise element definitions even when the element type definition is not classic. The following worked for me a couple of years ago with hp-approximation (and I hope still does), so you might consider trying it. For example, if we have split the entir...

Re: Damping in ElasticSolve Neo-Hooke model available?
Hi, I must say that I'm not an expert on material damping, but I'm giving some thoughts anyhow. The only damping mechanism which should be available in this connection is a version of proportional damping where the fully discrete equations are modified by adding the first-order time derivative term ...

Hi,
I guess you have already tried to give "Damping = Real ..." in the material section.
