I have the following error that is appearing in my work in %time domain
%time domain
1-tmin=0;
2-tmax=200;
3-dt1= ((2*D)/(U^2))-(deltax/U);
4-deltat=0.8*min([0.1,dt1]);
5-if deltat<0.01
6-deltat=0.01;
end
Line 6 deltat = 0.01;

Hi @Abdallah Alrefaie
The error message you’re seeing is typically due to a syntax error in your MATLAB code. In your case, the error message is “Parse error at ‘(’: usage might be invalid MATLAB syntax”. This suggests that there might be an issue with the use of parentheses in your code.
Check this code:
D = 1;
U = 1;
deltax = 1;
tmin=0;
tmax=200;
dt1= ((2*D)/(U^2))-(deltax/U);
deltat=0.8*min([0.1,dt1]);
if deltat<0.01
deltat=0.01;
end
Hope this helps.
