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 ! + DDOT_PRODUCT(...

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 ...

Re: Nonlinear elasticity

I’m interested in this topic too. Especially I can’t understand the following lines of Elasticsolove.src. ! Gateaux derivatives of the solution with respect to the displacement: ! --------------------------------------------------------------------- dDefGU = Grad dStrainU = (MATMUL(TRANSPOSE(DefG),d...

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"! Do you know a...
