    fortran (system commands)

    hi, i wish to know if fortran has commands like 'winwait' , 'winwait active' (i found these commands in Autoit) which can be used to run/automate windows applications. i am looking for developing a code which can run a third party program based on some 'IF conditions'.

    windows task automation

    hi, i wish to know if fortran can help in windows automation. the job expected is: fortran code (in exe) should invoke a third party software on windows10(call the 3rd party software as ABC). the input file for ABC is a text file, upon the completion of run, the fortran exe should read through...

    sacs query - wave load calculation

    Hi, I was calculating the wave load on a vertical pipe (OD=1.0m, Cd=1.0) using linear static analysis option in SACS. Wave parameters : Water depth= 26.6m, Wave ht = 3.486m, Tassociated =13.33s (stoke 5th order wave) I took the sacs output for horizontal velocity (at phase =0deg) and...

    mode participation factor

    hi, I am trying to calculate mode participation factors for a frame structure. the consistent mass matrix approach is used. I got the Eigen values, vectors, checked orthogonality - all ok. for calculating the mode participation, gamma=L/M, L is the coeff vector = [transpose(phi)]*[m]*[r]. how do...

    Invoke an .exe file using macro in excel

    Hi, i am trying to create an macro enabled excel file, in which , upon hitting the button, the excel gets saved to 'data.csv' into the same folder and an exe file is invoked (which is again in same folder) which will access the 'data.csv' for its inputs. i prepared this, however, upon hitting...

    precision while adding matrices

    Hi, I have a fortran program which generates 2d matrices A1(12x12) and A2(12x12), then combine it in such a way that A2(1,1) is added to A1(7,7), A2(1,2) is added to A1(7,8) and so on (as shown in the attachment). I got the output as matrix A (18 x18) from fortran. all the matrices are declared...

    doubt using dsygv

    hi, I am using fortran to get the Eigen values for generalized Eigen value problem of type Ax=lamda.Bx. I am using lapack routine dsygv for this and it works perfectly for all my 5 case studies and not working as expected for the 6th one. i get first two Eigen values as -ve which was not...

    Gnuplot export option

    Hi, I have gnuplot, which I use with fortran for ploting. I wish to know if a 3d plot generated in gnuplot using 'splot' can be saved as a dynamic pdf ? ie; whether I can rotate the model in pdf as I do in the gnuplot output window ? thanks

    eigen - dsygv

    Hi, i am using fortran to solve an eigen value problem. i am using lapack routine dsygv to solve the eqn of type (Ax=kBx). size of the matrices are 168x168, i am getting 'info' as 170 when i make the run - understand that this should be zero..could some one explain physical meaning of 'info'...

    reduction of stiffness matrix when spring fixity is involved

    hi, I have a vertical cantilever beam which is having spring fixities in all 6 dofs (at the base)... there is a load in vertical and in lateral direction at the free end.... after developing the stiffness matrix, how do i do prepare the reduced K matrix - basically, how do i solve for the...
