Please read my explanations above.
Abaqus produces output for every point on the model for every time step. Abaqus calls it the field output. If you are doing a time varying load, then filed output is very large.
If you are interested in output for only a few point, then you use the history output. For the history output Abaqus just output results for those point you asked for.
Thus the difference is the field output gives you everything while the history output is just for a few points. There are ways to control the amount data in the field output.
Since you have everything in the filed output, you can generate history output from them after the analysis has finished. This is not a good idea, but can be done.
Hi Hossam,
See Section 14.4.2 What is the difference between field output and history output? of Abaqus User manual
for field out put Abaqus produces output for every point on the model for a time varying loading with the frequency you assign ( reports too much put, but you can control it). History data refers output for a number of points which you decide with the frequency you like, which is exactly you want (much less data). You can generate history output from the filed output, as the field output contains everything.
I`ve read that section ,but i can`t understand it ,fully.
I need a simplified explanation

Hi,
Field Outputs refer to quantities distributed spatially over the whole model (e.g. stress field, strain field, displacement field , temperature field etc.), is used to
generate contour plots and animations.
History Outputs refers to quantities at specific points or quantities which characterise the whole model or a region of the model (e.g. elastic strain energy, energy dissipated plastically or other such quantities). It is used to generate more detailed time history plots than would be possible using the field output.
The two types of output are provided so that you can control the size of your results file while still obtaining all the information you need.
