Matlab is a very useful tool for post processing results obtained from OnScale. OnScale is able to export any time history or data array to a Matlab File with only a few lines of code.
Exporting Time Histories
When setting up outputs from a model, the form subcommand is used to export to Matlab. The following example exports 3 time histories to h1_data.mat.
form matlab h1 /* Write Time Histories to Matlab file (.mat)
histname electrode vq top1 /* Time History 1 & 2
hist xdsp $i1 $i1 1 $j3 $j3 1 /* Time History 3
hist ydsp $i1 $i1 1 $j3 $j3 1 /* Time History 4
The Matlab file is formatted so that the time history number corresponds to which column that data is in. So for this example Time History 1 (voltage on top electrode) would be in column 1 of h1_data.mat.
Exporting Data Arrays
The same form subcommand is used to export data arrays to Matlab. However, an additional command is required. The following example exports two data arrays to d1_data.mat.
file out filename.mat /* Assign Matlab file as Output file (.mat)
form out matlab d1 /* Write Data Outputs to assigned file
out modl /* Output Data 1
out pres /* Output Data 2
