Re: ElmerSolver input file

How do I make the two solvers interact such that the output obtained from the CoilSolver is used as input for the MGDynamicsCalc solver? Ajay, Are you talking of hierarchical coupling from CoilSolver to MGDynamicsCalc solver? http://www.elmerfem.org/forum/viewtopic.php?f=3&t=4351&hilit=hierarchical...

Re: adding youngs modulus as a function of stress

Hi, How about the concept of exporting stress as variable from the stress solver (with default displacement variable), and then defining young's modulus as a function of stress in Materials section. Please find how total flux and total area are exported as variables from Advection-Diffusion(concentr...

Re: Installing Elmer in Ubuntu 14.04 using Cmake

Daniel, 1. Those posts were written long ago and so , in recent OS or environment, things may be different. 2. I used to try with Method A, and if Cmake build type used to show up for me. Leaving the cmake build type = empty generally sets up the default parameters. 3. Currently I install elmer from...

Re: problem with long input in MATC?

Hi sage12, the MATC expression has a length limit of 128 characters ( http://www.elmerfem.org/forum/viewtopic.php?f=3&t=110 ). For expressions longer than 128 characters, we have to formulate a function (the function feature in elmer has no limit in length) and link it as a function in MATC expressi...

Re: How to specify current direction for a 3D rod that with turns

Hi srinathshiv, And to write MATC expression for trigonometric function, an example is provided as following: Current density 1 = Variable time Real MATC "1+sin(0.2*tx)" which,calculates and returns j_1= 1+sin(0.2t). For more details the MATC guide can be referred to: http://www.nic.funet.fi/pub/sci...
