import from .dat file abaqus
显示 更早的评论
hi all,
I try to import certain lines from my .dat file, generated from abaqus. However something strange happens. When I try to import the certain lines with use of Import Data button, select my lines and import it as a table and write it as a function 'importfile'. Then It's not importing the lines I want, but an arbitrary selection, even though the corresponding rows match. However if I copy and paste data from my abaqus generated .dat file, to an empty .dat file, open that one in matlab and select the lines I want to import, then it dóes import the correct lines.
Anyone a clue what is happening here? I tried almost all features in the Import Data toolbox, such as writing it as a different file (table, cell, etc.) but nothing works so far. The file is pretty large, can there be a problem?
I uploaded the file, I need the following data points, for every increment I need the values on the column below the PU2 and the frequency. Is someone keen to help me out? :)
NODE FOOT- U1 U2 PU1 PU2

Counter = 1;
FID = fopen('results.txt', 'rt');
tline = fgetl(FID);
File_Data{Counter} = tline;
while ischar(tline)
Counter = Counter+1;
tline = fgetl(FID);
File_Data{Counter} = tline;
end
fclose(FID);
File_Data = File_Data';
This will give you your file cell variable File_Data.
You will probably have to find a cell that contains 'INCREMENT NUMBER', example, Increment number is line 8, then you take 8-3, 8-4, 8 and 8+1 line for a single increment number.

I would not know how this code below would work, but you can use some ideas from it.
Wanted_Rows = 1:1:length(File_Data);
Delete_Lines = [1:13 114 115 216 217, length(File_Data)]; % Last line of File_Data is -1 which denotes end of file so we remove it here
File_Data(Delete_Lines) = [];
File_Data_Split = split(File_Data(1:length(File_Data))); % Splits the cell
Data_Ready = cellfun(@str2num,File_Data_Split);

Great to hear it works, KSSV's solution might be more appropriate when you would like to generalise the information extraction, without writing down the wanted rows like in that example.
