Re: stiffness
Hi Alex
is it the mechanical stifness in [N/m] you are looking for ?
I would take then a stationary sover on the structural mode on your model, load a face with 1 or 1000[N], or a pressureof p[Pa]=F[N]/(Area[m^2]), solve, calculate the average displacement by integrating disp_sm...[m] and dividing by the area and then calculate k[N/m]=F[N]*Area[m^2]/(int(disp_sm...)[m*m^2])
Or is it another varaible you are looking for ?
Good luck
Ivar

Re: stiffness
Hi Ivar,
Yes it is what I'm looking for..
before I used prescribed dislacement and calculated reaction force...
but I don't sure that my way of stiffness calculating is correct.
I will try your's.
Thank you,
Alex
