postprocessing with matlab

Post by alibrandi »

Dear all
I tried to use matlab as a postprocessor of a thermal transient analysis.
I opened the .ep file with excel,cutting the groupelement part and keeping only the grid coordinates and the temperatures at different timesteps.
Then I imported the data in matlab and rearranged them in a matrix that has a column for each timestep.
As the .ep file timestep output are in a single column that I had to split I think that this part can lead to some problems.
Do you know if it possible to rearrange the .ep in order to write the temperature at each timestep already in a matrix form?
Do you know if there are some other solutions already available to connect elmer and matlab easily?

Hi Alibran

Look at the SaveScalars and SaveLine auxiliary solvers (in Models Manual) for matlab-friendly output. For distributed fields (2D & 3D) we have not made any filters for Matlab since there is a good selection of dedicated postprocessors for FE data.

If you use the GUI you can take the solvers in to use by appending the xml definitions in edf-extra directory in File -> Definitions -> Append or by moving the xml definitions permanently to edf directory.
