win32 or win64?
Dear Elmer group Hi I’ve already received a modern computer with strong hardware. As far as I know it’s better to use 64 bit windows on modern systems to access all the CPU and RAM capacity. However, I wanted to ask if you have any idea about this matter regarding Elmersolver. Which one do you sugge...

Re: Stress calculation in axisymmetric FSI
Thanks a million Peter. Elmer is really best and unique.
I use WindowsBinaries from sourceforge.nt to install Elmer where The most recent available exe version is rev6064. Is there anywhere that I can find rev6299 WindowsBinaries? Regards, Hamed.

Re: Stress calculation in axisymmetric FSI
I added the following line to the solver part of the tutorial "Fluid flow around an elastic beam" and the same problem occurred again:
Calculate Stresses = True
I attached the tutorial files here. Regards, Hamed.

Re: Stress calculation in axisymmetric FSI
yes. I tried the following strategy:
Linear System Solver = Iterative
Linear System Iterative Method = BiCGStab
Linear System Preconditioning = ILU1 (and also ILU0,ILU3)
Linear System Max Iterations = 500
Linear System Convergence Tolerance = 1.0e-8
and the following error happened:
Linear System Solver = Iterative
Linear System Iterative Method = BiCGStab
Linear System Preconditioning = ILU1 (and also ILU0,ILU3)

Re: Stress calculation in axisymmetric FSI
Thanks a lot. It’s very good news.
However when I tried to calculate stresses in ElasticSolver the Elmersolver crashed due to the following error: ERROR: SolveBand: singular matrix. LAPACK DGBTRF info: 848
I attached the corresponding files below.
Best wishes, Hamed

Stress calculation in axisymmetric FSI
Dear Elmer friends Hi I need to calculate the solid stress in an axi-symmetric FSI analysis. But as far as I know stress calculation is not possible in nonlinear elasticity solver of Elmer. So I opted to couple linear elastic solid (via: Equation = Stress Analysis & Procedure = "StressSolve...

Re: Wall shear stress
Hi again dear Elmer friends I came back after two years and I feel really happy since I do love the fantastic Elmer. In fact, I'm looking for the file "shearratesolver.src" and/or some text guides or examples that helps using this solver (I'm trying to calculate the tube wall shear stress ...

Re: Neo-Hooke implementation
Hi Bengt The material model implemented in Elmer is the Saint Venant-Kirchhoff model (SEE e.g. chapter 5 of "Finite Elements for Nonlinear Continua & Structures, Belytschko" ). However, I should confess that there are many lines in the source code of subroutine "StressCompose"...

Re: Bubbles vs. Stabilization for incomp. flows
Hi,
I attached my testcase which is a FSI problem. I should mention that the problem happens when the time step becomes very small.

Bubbles vs. Stabilization for incomp. flows
Dear Elmer group I solved an incompressible flow problem with both bubbles and stabilized methods. The obtained flow velocity is the same in both cases but the pressure obtained by the bubbles method is 1000 time higher than that of the stabilized method. It’s my first experience of using bubbles me...
