Can I extract Stiffenes Matrix Equation and Mass Matrix Equation from Model that I have made?
You may enter the following command before the joint coordinates
SET PRINT STIFF
This will print the global stiffness matrix as part of the analysis output file. This command only works with the basic solver. So if you are using the advanced analysis engine license, you have to deactivate the license to run the basic solver. Alternately you may use the SET STAR 0 command before the SET PRINT STIFF command to run the analysis using the basic solver.
The program doesn't directly report mass matrix. If you have a modal calculation requested command or any dynamic analysis command as part of your file, you will find a file named file_name_MASS.TXT within the same folder where your STAAD.Pro model is located. It reports the masses lumped at the various nodes.
Thank you sir, I will check it
Nice I dint know about this feature. Thanks. When did you add this feature?
The feature has been there for sometime but has not been documented.
