Hi KaiMartin & Thomas,
Thanks a lot for the hints. I will give it a try again.
Regards,
Han

Elmer compilation problem on Cray cluster
Hello, I am having problems with compilation of Elmer on a Cray XC30 cluster. I've downloaded the source code from the repository git://www.github.com/ElmerCSC/elmerfem My installation script is: #!/bin/bash module swap PrgEnv-cray PrgEnv-gnu module load cray-libsci module load cray-tpsl rm -r CMake...

Source term of line integral form
Dear all, I want to model a heat source term within a cylinder wall, which basically reads http://i58.tinypic.com/16jrgx5.png The first term (f1) is due to heat release from a reaction modeled using Arrhenius form, which is temperature dependent. This can be easily obtained using MATC expression or ...

Hi LeeA,
Thanks. I will check on Calculix too.

Heat source as exported variable
Hi all, I have been puzzled by a problem with exporting heat source values for post-processing (I use Paraview, hence vtu format). This should be really trivial, but I can't find any solution so far. Using a simple test case of heat conduction in a 2-D square box with a Gaussian heat source in the c...

Re: Error in simulation using a user-defined boundary condition
Hi all, Just to confirm that I have found what the problem is. The bc code should have been written like this: convbc = - alpha_hot * (temp - Te) instead of convbc = alpha_hot * (temp - Te) & / (HeatCapacity(ParentElementNode) * Density(ParentElementNode)) and the specification in *.sif should h...

Re: Error in simulation using a user-defined boundary condition
Hi Peter, Another confusing thing that I have noticed. I compared the results of 2 simulations on a simple heat conduction problem across a square domain as illustrated in the following figure. http://i60.tinypic.com/j93p95.png The first simulation is the standard simulation with the following BC in...

Re: Error in simulation using a user-defined boundary condition
Hi Peter, Thanks for your reply. I can confirm that the simulation is now running, with the following: Boundary Condition 2 Target Boundaries = 3 Heat Flux = Variable Time Real Procedure "convRadBC" "convRadBC" Emissivity = 0.85 External Temperature = 850.0 Absorbance = Real 0.85...

Error in simulation using a user-defined boundary condition
Hi all, I am a beginner in Elmer. As a first trial to implement a user-defined boundary condition (b.c.), I made a simple b.c that combines convective and radiative heat fluxes, following these steps: 1. Referring to ElmerSolverManual (part: Basic Programming p89) about an example to implement a bou...

Re: Thermomechanical problem of a pressure vessel
Hi Peter, Thanks a lot for your reply. I agree that the isocurves of the stress fields agree with the reference, but only in the top and inner part of the vessel. If you look at the outer part of the vessel (which is made of an insulation material), the results in the reference show that the vonMise...
