HI Abolfazl Faramarzi

if you are using APDL you ca easily call Asys via Matlab using the following lie (you may change it according to your computer):

!SET KMP_STACKSIZE=15000k & "C:\Program Files\ANSYS Inc\Var145\ANSYS\bin\winx64\ansys145.exe" -b -p ANSYS -i C:\Users\kouider\Desktop\Ansys_INSIC_article_2\GA_opt_harVarester\model_opt.txt -o C:\Users\kouider\Desktop\Ansys_INSIC_article_2\GA_opt_harVarester\ansys_out.txt

I can help you more if you provide more details about your works

i the followig a exemple of a fitess fuctio that i have performed usig matla

function fit = fitness( Var )

% This function called the designed parameters as an input file

% The output is the energy

%==============================================================

% make sure the chromosome has no repeated coordinate couple (xi,yi)

for i=1:numel(Var)-3

if (Var(i)& Var(i+1))== (Var(i+2)& Var(i+3))

Var(i) = 10^(-1).*randi(4,1,1)+randi([0 1],1,1)*0.05;

end

end

%===============================================================

% Prepare the coordinate for the next use in ansys

Var1=Var(1);

Var2=Var(2);

Var3=Var(3);

Var4=Var(4);

Var5=Var(5);

Var6=Var(6);

Var7=Var(7);

Var8=Var(8);

fid=fopen('parametre.inp','w+');

fprintf(fid,'Var1=%f\n',Var1);

fprintf(fid,'Var2=%f\n',Var2);

fprintf(fid,'Var3=%f\n',Var3);

fprintf(fid,'Var4=%f\n',Var4);

fprintf(fid,'Var5=%f\n',Var5);

fprintf(fid,'Var6=%f\n',Var6);

fprintf(fid,'Var7=%f\n',Var7);

fprintf(fid,'Var8=%f\n',Var8);

;

fclose(fid);

% Calculate the Varalue on the obj function

format long

fidn=fopen('VarLG.txt','r');

Varlt=fscanf(fidn,'%g',[130 1]);

fclose(fidn);

R=1e7;

for i=1:129

eng(i)=(trapz([i-1 i],[Varlt(i).^2 Varlt(i+1).^2]))./(2*R);

end

fit=sum(eng);

end
