Re: Nonlinear elasticity
Hello I'll be really grateful if somebody can help me understand the following lines in the "StressCompose" subroutine: Newton iteration: ! ----------------- StiffMatrix(dim*(p-1)+i,dim*(q-1)+j) & = StiffMatrix(dim*(p-1)+i,dim*(q-1)+j) & + DOT_PRODUCT(dBasisdx(q,:),dStress1(j,:))*s...

Re: Navier-Stokes equations
Hi
What are the default values for ‘divdiscretization’ and ‘gradPdiscretization’ in Navier-Stokes solver for incompressible flows? Are they "True" or "False"?
Regards,

Force i in elasticity solver
Dear Elmer group
Hello
What does the keyword “Force i” in elasticity solver refer to? Is it a distributed pressure on a boundary line/Surface or is it a point force? Should it be applied on a boundary (line or surface) or on a node?
Best wishes,
KimSongOik

Re: axisymmetric nonlinear elasticity solver
Thanks. I had a look too. The “axisymmetric” keyword exists in several parts of the code, however I couldn’t find the associated matrix developments (e.g. the elastic coefficients matrix) for axisymmetric case. In fact I’m trying Nonlinear Elastic Solver. It works fine for Cartesian problems but in ...

ElmerGrid sudden crash
Dear Elmer Hi I usually make my model mesh by ANSYS, but when the number of elements and nodes (or in other words, the size of exportmesh files) becomes large (in 2 or 3D problems), ElmerGrid crashes during executing the command "ElmerGrid 4 2 exportmesh" or "ElmerGrid 4 3 exportmesh&...
