Elmer Discussion Forum

I see I have just been running multiple commands at the same time instead of spreading the load.
So there was no time win at all.

At least now an error message is shown.

Sorry for taking your time with my wishful thinking.

Hello, I have updated one of the pc's here to Ubuntu 14.04 and reinstalled Elmer. It doesn't seem to be using multiple cores. I have certain computations that do not use partitioning of the mesh. In the past I was able to run this simulation on multiple cores using mpirun. This is still the case on ...

The simulation works on a 13.10 machine I have in the office. So it seems to be specific to my ubuntu 14.04 install. I'm a little apprehensive of building Elmer 7 on ubuntu 14.04 I have seen a lot of issues with it here on this forum. http://www.elmerfem.org/forum/viewtopic.php?f=3&t=3585&p=...

I think this is related to the fact that I'm running Elmer on Ubuntu 14.04 When I run elmerf90 -o Jintegral.so Jintegral.f90 I get: gfortran -I/build/buildd/elmerfem-6.1.0.svn.5396.dfsg2/debian/tmp/usr/include -fPIC -m64 -fPIC -fPIC -I. -Ibinio -I/usr/include/mpi -I/usr/include -m64 -fPIC -I/usr/sha...

I've tried out the code but it's giving me a segmentation fault.
The code runs and even outputs something interesting. I've included the elmer output.

I doesn't give me any hint whay might be wrong except for: Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

Regards,

Thank you all for your answers, I have ElmerGUI working now on Ubuntu 14.04 I only really need to use the GUI sometimes to check if my mesh is correct. It is a good way to verify boundary numbers. However, I also do like the convergence plot it makes during simulations. Is there a way to view the co...

Hello, I've just switched to Ubuntu 14.04 I can install Elmer solver etc. from the repository, however ElmerGUI is not included. I read somewhere that ElmerGUI is not included because of licencing issues with opencascade code which it uses. What is the best way to install ElmerGui on my machine? Whe...

Hello, With help of the example you pointed out I've made some progress. My simulation is running and it is giving me good result. What is the best way to handle simulation steps that do not converge, i.e. are past the pull-in step? I'm using a resultoutput solver to export a vtk after each voltage ...

Hello, I would like to perform a coupled electrostatic - mechanic simulation to calculate pull-in of a fairly complicated (comb-drive) electrode. The mesh will be generated by gmsh. How will the update mesh for the coupled simulation work? I would like to remesh it with gmsh and not have to dig into...

Hi, I can't get the connect flag to work, i'm not getting any feedback, just a segmentation fault (core dumped) Also, with this mesh, the 3: METIS PartGraphKway routine doesn't seem to work. I've included the mesh, the output of gmsh and in elmer format, and a picture. The (periodic) boundary condit...
