Can you please tell me if there is any standard syntax to Intrigate and
derivate any value (velocity in this case) with respect to time to get
displacement and acceleration of the damper.

You can find information on the web more easily using the proper words
and spellings: "integrate" and "differentiate".

Differentiating a function via finite differences is simple to program.
An alternative is "automatic differentiation", which uses a program to
write Fortran code that calculates the derivative. I have read that
this can be faster and more accurate than numerical differentiation,
but I have not tried it.
