Dynamic simulation .out to matlab

Hey guys

I have been using excel to manage my .out files but I want to import the data into matlab now since the datasets are getting bigger and bigger.

Is there a function that would do this for me similar as dyntools exports to excel.

Best Regards Johannnes

There isn't a ready-made function. But you could write something that exports to CSV. Then import that to matlab. Does it take a long time to write to excel?

Hey man, I am currently exporting all the out files and the channels I want to excel and then I should be able to open it in matlab but that is a alot of mouseclicks :)

I actually noticed an interesting problem. When I run many dynamic simulations the size of the .out files seem to grow althoguh I change the name and reopen the channels so I can run limited amount of dynamic simulations.

Yeah, sorry I wasn't much help on that one. My suggestion had more to do with writing directly to a flat CSV file and then in Matlab reading that CSV file in. This way you skip Excel entirely.

Hello,

I do you read the .out file in Excel? Mine is just a bunch of garbage.

Best Regards,

Hey Madje Yes I use dyntools to export the .out files and the channels I want to excel. Best Regards Johannes

*Copying of all channels into matlab workspace (as possibility for matlab users)*

Download matlab function and example of using:

https://drive.google.com/drive/folder...

function [numberchannels,nameschannels,tomatlab]=pssout2matlab(inputfile)

nameschannels=[];

channelsdata=[];

numberchannels=[];

tekst=[];

if nargin==0

[filename]=uigetfile('*.out','PSSE .out files'); % select file from disk (without inputfile in function call)

fid=fopen(filename);

else

fid=fopen(inputfile');

end

setstr(fread(fid,4,'char')');

setstr(fread(fid,4,'char')');

setstr(fread(fid,4,'char')');

numberchannels=fread(fid,1,'float32');

fread(fid,1,'float32');

nameschannels=setstr(fread(fid,[32, numberchannels] ,'char'))';

nameschannels=strvcat(strcat('Time',blanks(28)),nameschannels);

tekst=setstr(fread(fid,[60, 2] ,'char'))';

channelsdata=fread(fid,Inf,'float32');

kolona=(size(channelsdata,1)-2)/(numberchannels+2);

rezultat=reshape(channelsdata(1:kolona*(numberchannels+2)),numberchannels+2,kolona)';

tomatlab=rezultat(:,2:size(rezultat,2));

fclose(fid);

numberchannels=numberchannels+1;

nameschannels=strcat(num2str([1:numberchannels]','%06.f'),'-',nameschannels);

end

Johannes.Thorleiksson, you have to delete all channels after one dynamic simulation, and then again set channels using python... then the sizes of out files doesn't grow during simulations
