So first define a frequency dependent table for the stiffness called say k_freq using *dim that holds the stiffness values as function of freq.
Define the combin14 using ET command
Assign real constants for stiffness using the table k_freq as:
or if in mechanical in the command snippet below a spring object (under connections/spring)
Please see the *DIM. R, RMODIF, and ET commands for more info.
ALso have in mind that this can only be used with a
All the best
