You can bring the data from FLAC to Excel using following steps.

I. In the FLAC console, print the variable data (e.g. in a triaxial test, I can record the history of deviator stress 'devstr' and axial strain 'astr'. In console, I can give a command 'print devstr vs astr', which displays the values in two columns.

2. Copy the data from screen into a notepad, say "test.txt".

3. Open Excel and open file --> all files --> test.txt

4. A text import wizard will pop up, where you need to select "delimited"  and then --> next and then select all delimiters --> OK

5. Your FLAC data is now imported to Excel. You can draw any plot using this.

Obviously, the answer from Madhavi Latha Gali can give you and me great help.

Thanks.

Hi Mohammad,

Madhavi explained the solution very well. However, if you do not have a FLAC software or unable to open the graph, you can use Digitizeit software. In this software, you can import your graph and by simply selecting points you can get a digital form of it.

Hope this helps !

Just put the command line" history " number" write filename.txt . and a text file will be saved in the project folder. For more details see the command reference

 Hi everybody

how about a history plot?

Prof. Madhavi latha, is it necessary to define the variables by fish function to obtain the plot?

Because, i am getting the stress values at each grid point along i*j matrix.

I am not getting the two columns that you have mentioned.

Any suggestions please.

Try this example code. You will see the two columns dumped in your console. Yes, you should define fish functions to obtain axial strain (ev below) and deviator stress (s1_s3 below). 

config axi

grid 5 10

gen 0,0 0,0.038 0.019,0.038 0.019,0

m m

prop den 1800

fix y j=1

fix x i=1

ini sxx 100e3 syy 100e3 szz 100e3

apply press 100e3 i=6

apply yv=-3e-7 j=11

prop coh 2.25e3 fri 33 bulk 1e8 shea 0.3e8

def s1_s3

sum=0

loop i(1,igp)

sum=sum+yforce(i,jgp)

end_loop

sigmav=sum/(x(igp,jgp)-x(1,jgp))

s1_s3=sigmav-100e3

end

def ev

ev=(-ydisp(1,11))/(y(1,11)-y(1,1))

end

hist nstep 100

his s1_s3

his ev

step 10000

his dump 1 vs 2

Thank you Prof. Madhavi Latha for clearing the doubt. I got it now

Thanks a lot for the code.

Thank you Prof. Madhavi Latha for the time you spent responding to this question. 

Absolutely correct

Assume you want to observe the vertical stress and pore water pressure at point that have coordinate (x,y,z) = (0,0,0)

his add id 1 gp szz 0 0 0

his add id 2 gp pp 0 0 0

his add id 3 gp dytime ; change to fluid or creep time depend on problem you config

his dump 1 2 vs 3 file stress-pwp-vs-time.txt

After execute there is a .txt file in your project directory that have the data you want. It is easy to compare many time series afterward.

As some of the colleagues recommended here; You may use a simple and free software such as "Web Plot Digitizer" which can provide you continuous data of your graph in a matter of seconds :)

Hi , does anyone know how can I express the output of a certain node of a structure element ? for example, if I want to put the value of the moment of node 1 in an array, what is the keyword that I should use ?

Hi, anyone knows how to get deformed shape? I have modelled 3d concrete getting deposited according to time and I am getting all deflection value, stresses but I want deformed shape as per Mohr coulomb.

The deformed shape in FLAC 2D can be found out by giving the command:

plot grid magnify 2.0, where 2.0 is the magnification factor (or the scale of the deformed shape).
