Hi,
I will appreciate you , if you could guide me how can I add off-diagonal mass to the Mass Matrix?
For example:
Current Mass Matrix
a 0 0
0 b 0
0 0 C
After Adding off-diagonal mass to the Mass Matrix :
a 0 0
0 b+d -d
0 -d C+d
Thank you in advance for your time and consideration.
best,
Adding the off-diagonal mass to the Mass Matrix
