Image to video conversion and vice versa in linux using ffmpeg command 1. Video to image conversion (sequential images) $ ffmpeg -i inputfile.avi -r 0.25 image_%04d.png Here, r is the framerate (4 images per 1 second) 2. Image to video conversion (sequential images) $ ffmpeg -r 5 -i image_%04d.png ...

Dear Kevin,
Thanks for your wonderful examples of testing youngs modulus as a function of variables.

Yours Sincerely,
Anil Kunwar

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...

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...

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...

Hi Juan, It seems elmer non-gui version has been successfully installed in your Ubuntu system, from the abovementioned command. $ sudo apt-add-repository ppa:elmer-csc-ubuntu/elmer-csc-ppa $ sudo apt-get update $ sudo apt-get install elmerfem-csc I use non-Gui version, and it is very efficient. The ...

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...

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...
