Elmer Discussion Forum

Hi

Could it be that you were running the virtual machine including Elmer binaries and all related software.

If you install your own native Mint you need to add these software separately.

Hi

Have you tried installing from:

Hi awarru It seems that my knowledge was a bit outdated. I thought that FTDT was used because of nonlinear tissue properties but perhaps it was used simply for the fact that it is the easiest method to code. The complexity of FTDT is a fraction of that of implicit FEM. If there is no need for nonlin...

Hi

Having the initial mesh file would help.

ElmerGrid is compiled usually with ElmerSolver so the version follows that. The changes is not that many on ElmerGrid, you can see them in:

Yes, it is the capacitance computed directly from the energy assuming voltage difference given by the min and max potential at the boundary. -Peter

Hi

Rather than loading the project go to the project directory and simply call "ElmerSolver" on command line.

The project file is unfortunately version depedent. The sif file on the other hand is always backward compatible.

Hi Nice picture! Capacitance between i and j are is defined such that Q=C_ij(U_i-U_j), for example. In your picture you don't have the system in single potential. Hence the potential matrix might not be directly applicable to this as it automates the permutation of unity potential and uses those to ...

Hi Kumar,

Good theory. Except that I think that before going to solver Ax=b the routines check for case |b|<eps since in that case x will have the trivial solution zero.

What if you try with direct solver?

Hi I think we have two different issues here. a) The original problem may come from the fact the the menu structures were appended but this was not done before reloading the case. It is often more convinient to copy the interesting xml files to directory $ELMERHOME/share/ElmerGUI/edf-extra to direct...

Hi Kumar,

Maybe you could share a minimal version of your problem. It is hard to capture the potential bugs simply by viewing the sif file.
